I weaned from 900 mg Gabapentin daily to none in about 3 weeks. Pharmacist said I could do it quicker, but I had severe dizziness when I did, so kept taking 100 mg twice a day for about a week after that, then one a day for another week. I had headaches for about a month afterwards but it they finally subsided. It had started causing weird eye movements and was making my brain foggy so decided to stop it.
