Yes, Llama is right...Lamictal is a med that has to be increased slowly and if you are to come off of it you should come off of it slowly too. How much Lamictal were you on before you took yourself off of it???
I know that you had reasons that you felt you should stop this med but perhaps a few more days at a little lower dose could have allowed you to adjust to it and then increase it more slowly. It's a great med with minimal side effects and the pdoc would have advised you what to do so that you could give the med a fighting chance.
I don't mean to make you feel bad....it's just that there are so few opportunities to find the right meds and they all have side effects in the beginning that our bodies have to get use to. My daughter started blacking out on Seroquel and the pdoc told us to give her something salty and a glass of water and promised that she would feel better the next day....I had my doubts but she was right!!!
Hope that you are feeling better soon and that you find a med that brings you stability.
