I took Lamictal for several years. I've been off of it for a while now (at least 4). I started taking it because my (then) pdoc wanted me on a mood stabilizer but didn't want me on anti depressants and I had severe side effects with a few other mood stabilizers.

I can't remember my exact dosage but I went up gradually and found that at one point I had to go back down to a lower dosage because it was triggering hypomania. However, the Lamictal and Seroquel kept me able to function and eventually the pdoc took me off the Lamictal and I took Seroquel only for a long time (However now I'm taking it with Klonopin for anxiety issues).
