Has anyone been on gabapentin and experienced tremors? To deal with daily headaches, my neurologist went from I think 900 mg a day to 2400 mg a day. It has helped considerably with the headaches (but they are not completely gone and I still need fioricet or lortab when they get bad) , but I think the increase in dosage may be causing tremors in both hands, along with blurred vision (particularly up close). Blurred vision is stated as a possible side effect on the bottle. At the same time, I have been tapered off Kepra and am tapering up on Lamotigine. Not sure if that may have something to do with that or not? Any experience or advice?
