I have been on tegratol for almost 1 year now and have put on about 15 pds, mostly in my mid-section. Very upsetting as i cannot seem to do anything to get it off. Has anyone had any success losing weight while on tegratol- how did you do it? I am about to get pregnant, so changing drugs is out of the question. Do not want to carry around excess weight during pregnancy. Also, does increased dose affect weight gain?
