I took gabapentin (generic neurontin) for a while to help with sleeping but my dose was uncharacteristically low, 200mg. Even then it whacked me out for the first week until we played with timing and my system adjusted a bit (I started much higher, went to 300mg/day then to 200 just at night). My neuro laughed as he just Rx'd to another patient 2400mg and had to double it so maybe this is the track your doc is on? We all metabolize this crap differently; it seems that my system is very sensitive to it. I stopped after a few months, when I could sleep through the night and not wake up my hubby by spasming in my sleep and such. It was also time to up the dose since my body was getting used to it. The neuro's didn't want me to stop it, since it was 'working', but it was making me forgetful and it also slows other contractions (colonic) and over time that can cause problems. I didn't suffer from going off it but felt better - it was nice to be able to retrieve info again and not feel like a ditz. The main point is that it allowed me to sleep and that added immeasurably to my general well-being; sort of got me over a bad spot so I could start healing. So even though I'm not at all into pharmaceuticals, in this case it was the right move for a short time frame. Knowing some people who have had to take these types of drugs for many years (i.e. epilepsy, etc), they say that they have to occasionally be switched out and one must be very careful of over-drugging as more is not always better especially when you are mixing them. It takes a lot of fine-tuning due to the highly individualistic response.
