My doctor has me on 2 900mg of Gabapentin 3 times a day. I heard that anything over 1200 mg a day doesn't really do much. I also have severe insomnia and am on Temazepam 30mg but since my dosage of Gabapentin was increased they don't work at all. I only sleep like twice a week. Does this have something to do with the extremely high dose of Gabapentin.
