I have only been taking Lamictal for one week and so far I have had no severe side effects. I have been sleeping better at night (I take it in the morning) and am starting to feel better. Less angry and irritable. I was diagnosed with bipolar ll. The last few days I have had pain in my hips and have had to take Advil for the pain and now I am having a little bit of chest pain. Overall so far though I would say that the benefit of feeling better is worth the pain....
