Why are you taking it? Are you on the generic or name brand? There is a big difference in reaction time in the two.
I started taking it for nerve pain. When I started having seizures, doc just upped my dose. Seems everytime I try to get off it, the pain sets in again. Currently taking it for both pain & seizures. The dry mouth is the pits. Be sure & brush your teeth often. It can cause your teeth to rot out. KK
