Ii have been taking Lamictal 25 mg,, 3 in the evening and I in the morning. For headaches, along with Topamax and Buspar.I have been on Lamictal for at lease 15 years. My question is, now I have severe body aches bad muscle ache, which we think could be coming from the Lamictal. Could I gradually take myself off the Lamictal for awhile?
