I have always had trouble going to sleep or sleeping during the day. When I started taking Gabapentin I sleep a lot. This morning I woke up at 10am and could have gone back to sleep. I started out at 3 X 100mg then Feb 6 X 100mg and now 9 X 100mg. I cut back to 700 but still tired all the time. Is this normal. I'm wondering if I have mono again?
