When Pain Killers Don't Cut It

Erowid user confesses to possible addiction to opioids for kidney stone pain. Commentary to follow quote.


http://www.erowid.org/experiences/exp.php?ID=22485

I came online tonight searching for answers to my questions about the myriad of drugs I am currently taking, and thought my experience so far with these drugs could prove useful to someone in my position in the future. I have had been passing kidney stones for the past week - the most painful experience of my life - and in between my many trips to the ER, I have been given oxycodone, toradol and dilaudid to control the pain.

I am extremely afraid of developing an addiction to these drugs, as I have an 'addictive personality' and have had drug habit problems in the past. It's been a difficult situation because the onset of kidney pain sends me into such a fright that I pop the maximum amount of pills that I am supposed to take at once. I am afraid that slight pain I begin to feel will worsen until I am in the state I was in the first day I had the stones - a pain that I would not wish upon my worst enemy. The pain had me reduced to a blabbering, crying mess. When I got to the ER that day I had no control over my words and actions, and I was screaming and moaning for painkillers. When I finally got my shot of toradol and dilaudid I was in heaven...and I tried so hard to convince myself it was just from the pain relief, not from the drugs themselves.

I finally left the hospital that day and continued to have bouts of pain that would sometimes be relieved by the prescriptions, and sometimes not. By the fourth day, I noticed the meds were having no effect whatsoever. It scared me that I already was having such a tolerance to the meds, especially because of how strong I was told dilaudid was. Was it the strength of pain or my tolerance to the meds? I don't really know. I just got home from my third visit to the hospital in the past week, except I had to stay overnight with a morphine drip to control the pain. I was later switched to oral medication - oxycodone - and I was able to handle the pain that way so I got sent home with 30 more pills.

There is no real point to my story except that I question my actions...at the slightest possibility of my beginning to feel twinges of back/abdomen pain associated with kidney stones, I take the oxycodone, toradol, and/or dilaudid. I really don't know if it's more because I am afraid of having pain like I did, or because I am developing an addiction to these pain killers. I must admit that the pain killers make it so much easier to sleep, and as soon as I feel the 'coming down' effects like increased sensitivity (crying at the drop of a hat) and increased annoyedness (especially at loud noise), I feel compelled to take the drugs. At the same time, however, these drugs do not provide all bliss to me either; I experience intense itchiness, mild nausea, and an overwhelming grogginess that brings about a depressed mental state. I personally feel much better having written this, because I think I am being a lot more honest with myself, and have realized that I have caught myself giving in to an addiction...




Commentary: Acute pain caused by kidney stones is never remedied by opioids, except when the user is asleep. Had the Emergency doctor been on the ball, had she co-prescribed hydroxyzine or suggested an OTC antihistamine such as Benedryl (diphenhydramine), Chlor-tripolon (chlorpheniramine) or even cetirizine (which has not sedative properties but being a metabolite of hydroxyzine) does moderate opioid potentition, the user would have experienced pain relief earlier once the sedation of the antihistamine kicked in. This also implies less opioids can be taken to relieve the pain.

As shown in the above case, the person reporting his experience with opioids is under great pain, and under these circumstances, tries to dull the pain. Adding an antihistamine to lessen his dose of opioids would complicate matters i.e. scheduling when to take it and how to tell the difference between an antihistamine and an opioid. So the combination would only be useful in a hospital setting where dose scheduling could be better controlled.

This is why antihistamines, especially first-generation such as Benedryl, Chlor-tripolon and hydroxyzine, are usually not given to people with their pain medication due to the risk of overdose.

This is also why tobacco products are addictive, because of the synergy between the nicotine (an acetylcholine agonist) and harmaline, a central nervous system (CNS) stimulant and a reversible inhibitor of MAO-A (RIMA), contained in cigarettes and other tobacco products.

A RIMA prevents the breakdown of neurotransmitters, especially acetylcholine, adrenalin, dopamine, GABA, noradrenalin, serotonin, and tyrosine.

As a RIMA, harmaline also prevents histamine (a monamine) from breaking down. In high doses, with susceptible people it might cause hallucinations because of this action by preventing the breakdown of endogenous dimethyltryptamine. This is not true in all cases.

Nicotine itself too is a CNS stimulant, though its metabolite cotinine is both an anti-psychotic and nootropic.

Flaxseed: Lignans and Protein Reason for Health Benefits?

http://en.wikipedia.org/wiki/Lignan
http://www.dietaryfiberfood.com/lignan.php

Lignans are phytoestrogens with a phenol group as organic radical. By adding an amine to a lignan, a neurotransmitter may be formed. Though cell metabolism would prefer phenylalanine or even better tyrosine as precursor to dopamine. Meats are a good source of phenylalanine and tyrosine.

http://en.wikipedia.org/wiki/Phenylalanine

Phenylalanine is found in plant and animal protein.

Additionally, dopamine has in addition to its role as neurotranmitter in neurons, a neurohormone effect in the hypothalamus, which controls mood, behavior and appetite.

http://en.wikipedia.org/wiki/Dopamine

In contrast, acetylcholine has an amine added to the acetyl group. Its role is neuromodulation i.e. moderates the dopamine and serotonin levels due to its slow breakdown. Usually acetylcholine accumulates in cerebral spinal fluid (CSF).

http://en.wikipedia.org/wiki/Acetylcholine

Choline is found in lecithin which is found in most animal meats and plants. Good food sources of choline include eggs, beef, chicken and turkey. Although animal proteins are the highest dietary sources of choline, vegetarians and vegans can obtain adequate choline through wheat germ, beans, Brussels sprouts, broccoli, collards, cauliflower and soy milk.

As for tryptophan, it consists of an indole radical, propanoic acid and an amine. The body metabolizes it into serotonin in the gut.

It is found in protein from both animal and plant sources. Fish contains the most healthiest source of tryptophan, along with beans, nuts and seeds, and milk products.

Thiamine at 50 mg good for "mental acuity"

The RDA [for thiamine] ... is set at ... 1.4 mg. However, tests on volunteers at daily doses of about 50 mg have shown an increase in mental acuity.

Not only does thiamine keep the pests like fleas and mosquitoes at bay, it also makes the mind more acute.

"Thiamine is used in the biosynthesis of the neurotransmitter acetylcholine and gamma-aminobutyric acid (GABA)." — Wikipedia entry for thiamine

"One well-supported function of acetylcholine (ACh) in cortex is increased responsiveness to sensory stimuli, a form of attention." It helps improve hearing, sight and body-sense.

Learning and neuroplasticity is dependent on acetylcholine. It also help improves response to behavior cues.

GABA helps in the formation of synapses, thus improving neuroplasticity.

As for toxicity, high doses of thiamine are safe and harmless.
