I am bipolar and have been taking Lamictal for 2 to 2 1/2 months, worked my way slowly up to 200 mg/day now. Finally thought I was fine and maintaining well. A few days ago I started getting dizzy and light-headed. I've been going through a lot of stress and thought the dizziness might be because I'm smoking a lot now. This is what I've noticed besides the dizziness (I am dizzy right now): YELLING OUT during sleep (can't stop myself) and waking myself up some nights, stomach aches (may be due to diverticulitis that I have), sores in my mouth (two so far), irritibility and anger so bad I can't believe it (on two occasions recently), Cystic Acne on my face, also I have been confused, clumsy, and at a loss for words (very bad). Have tried to call my doctor today and her nurse, no luck. Will try again tomorrow. I went through hell, five medicines from January to September of this year, and I dread changing again. The holidays are here; my birthday, Thanksgiving, and Christmas, and my daughter and grandson are coming for Christmas from another state. I think that I would rather endure the side effects than try another med right now. Good luck to you all. A good doctor can make all the difference, but one must still go through the valley of death when one must change meds.
