Hello, this is my first post. I have Bi Polar disorder and was diagnosed about two years ago. I was on 100 mg of Lamictal and it wasn't doing anything for me. My doctor brought it up to 200 mg. It did a great deal for my mood. I felt good and enjoyed doing things again. I wasn't hitting the lows I was before. I also take 10 mg of lexapro for depression. The only problem with taking the 200 mg, since I have had troubles sleeping and my tourettes is really bad(facial ticks and little things like that). Is lamictal a stimulant. I really don't know anything about it. Because a stimulant like coffee or caffeine make my ticks very bad and it is very annoying. Any help would be appreciated. I don't know anybody else with bipolar and tourettes so maybe there aren't many of us out there but we'll see. Thanks in advance.
