Yeah, I took Lamictal (highest recommended dose) for years and then began to have problems with walking and facial twitching. My GP thought that I might have a toxic level in my system, so I was taken off of it. That meant I was on no mood stabilizers. I have been on all kinds of drugs over the years--anti-psychotic, anti-depressant, and mood -stabilizing....I am hoping that this will work out! Thanks for responding. I hope my doctors will check my blood from time to time....
