I was on Lamictal for about a year and it didn't do too much for me but was being used in combination with a few other meds so that gets hard to tell. There aren't any meds that are going to "cure" your mood swings. By that I mean you're going to swing up and down more than the average person but the meds try to keep you within a set point to avoid the extremes. It could be that this is a cycle for you and like was already suggested, the Lamictal is keeping you contained (bad choice of word but I think you get my point). If it continues to be a problem though I would talk to pdoc and see if he/she wants to add in another mood stabilizer with it. That happens from time to time. Take care!!!
