i just joined this board also. i left tegretol and lamictal today and started on topomax. i've been on tegretol for 5 or 6 years now. i have felt the same thing and because of some things happening in my life, the last 3 or 4 weeks have been terrible. i've felt stoned, tired, depressed, etc.. i'm not seizure free either. i'm a little nervous to try the topomax.
