Lamictal/lamotrigine High...?

My neurologist just increased my lamotrigine from 150mg to 200mg twice a day. I ramped up slowly and I’ve been at this new dose for about 2-3 weeks. Every day I can tell exactly when my medication is in full swing because I get really drowsy, and I feel kind of high, like suuuuuper relaxed and flighty and sort of in slow motion or something (similar to Xanax, if anyone takes that). I didn’t feel this way with 150mg, but I had a seizure while on that dose, which is why it was increased. The only other medicine I take daily is birth control, which never had this effect on me. It also doesn’t matter if I take lamotrigine with or without food—I get this high feeling every day no matter what. I know 200mg twice a day is a fairly average or even low dose, and the last time I was at this dose was when I was first diagnosed with epilepsy over ten years ago in high school (and to be honest, I don’t remember much of high school after I started taking it because it also gives me memory problems). I got laid off recently, and I’m a little worried about getting back into the workforce if I’m feeling like this every day, especially when I can drive again. Does anyone else get this feeling, or anything similar??
