I would be very careful with the Tegratol. My 17 year od son just came out of a very rare allergic/auto immune reaction to Tegratol. It is called DRESS, it is very similar to Stevens Johnson Syndrome. Loss of appetite, shaking, weight loss and dark smelly urine are all symptoms. If you develop a high fever, and a sunburn like rash over your body so to the ER.
Good luck.
