Lamictal and hot flashes

I've been on Lamictal for 3 years after a brain tumor removal. I was intially on Dilantin but the side effects made me crazy. My face constantly tingled and was numb, I couldn't speak well and the dizziness was debilitating. My neuro put me on Lamictal. I started off at 100mg, once in the morning and once at night, and had another seizure. I finally figured out I was having my seizures in the late afternoon and deduced the drug was wearing off around that time. My neuro put me on 150mg 2x a day and 100mg at lunch time. I've had no seizures for 2 years and 3 months so I think we have the dosage problem licked. However, I am really dizzy in the late afternoon and if I get excited like when I'm at a party. Shopping makes it much worse and I think that is due to moving my eyes around so much. Grocery shopping can be a tough task. I don't slur my words but I frequently cannot 'find' the right word. I'm slower in everything. I cannot take a walk looking at the horizon because I lose my balance and get dizzy again. Sometimes my head tingles. Heat makes it worse and when I get hot flashes (yes, I'm over 50) makes the dizzy much worse. Sometimes my fingers don't automatically go to the home key on the computer keyboard. I have to really concentrate on things that used to be automatic, like knowing a stop light is red. I used to be able to 'see' that and react appropriately. Now I have to concentrate on those red lights so it is irritating. I feel like I'm getting old. However, I will stay on this medication. It works and though the side effects are tough to live with, I'd rather stay on a med that I know works, rather than try one that might work. I lose my driver's license every time I have a seizure. I guess that is the worst side effect :-( I'm hunting for something to combat the dizziness and am using mybraintrainer.com to see if brain training exercises will help me become faster again. It can't hurt and so far I've had a little bit of success. I'll just keep going.
