Gabapentin was initially synthesized to mimic the chemical structure of the neurotransmitter gamma-aminobutyric acid (GABA), but is not believed to act on the same brain receptors. The mechanism of action that leads to its rapid analgesic effect is simply unknown.
So now that you know a little bit about Gabapentin let me tell you how this drug can save you from the worst part of opiate withdrawals (being the first three days) Gabapentin when taken at high doses (1800 mg - 3600 mg) will completely take away the discomfort of withdrawals. The only problem with the drug is you build up a tolerance fast. On the first day start with 1800 mg, the second day 2400 mg and on the third day 3600 mg. After the third day gabapentin will do you no good. Not only does it help with withdrawals but it makes you feel good, more social, lights seem brighter, basically it's a good time. Gabapentin is prescribed a lot for a lot of off label uses (uses not approved by the FDA) originally gabapentin was prescribed for seizures and later for nerve pain but is now prescribed for everything from bi-polar disorder to migraine relief. Doctors have no problem prescribing this drug because it is non-narcotic so if you ask your doctor for it to help with withdrawals he'll probably give it to you or you could always tell him your having migraines. Other than that you might very well know someone that is already prescribed it and get some from them (taking other peoples meds is illegal and you do it at your own risk)
