I wonder if anybody has this side effect besides me. Occasionally I will get so sleepy I could just sleep hour after hour after hour, and usually after a day of this feel fine. Lately seems to be happening when I try to read a lot. Today about 4 I needed a nap and then all evening could not keep awake. Got up for a while but can feel I'm going right back to sleep when I go back to bed. I have no seizure activity, just this horrible tiredness. Really really do not know how you guys cope that take more meds than I do and especially more than one kind. Just cannot fathom how you even live any kind of life.
