Insomnia
"I&#039;m going to echo what most of the other posters her have said and say that Gabapentin can be effective for insomnia, but with a few caveats. I was prescribed 300mg/night by my doctor to help with insomnia induced by opiate withdrawals after recovering from surgery, and on the first few nights it seemed to work reasonably well. However, I did notice that my tolerance to its sedating effects built up rapidly, and by night 4 on 300mg my insomnia reared its stubborn head again. By night 6 I was determined to sleep well, so I upped my dose to 600mg. The result was the first solid 8 hour block of sleep I&#039;ve had in over a month, but after only two nights of quality rest, I woke up at 2:30am again today. So, beware tolerance build-up!"
