Don't give up. People can and do get better with TBI. If none of the meds are working.... I would seek another physician. Maybe that many are doing you more harm than good. Have you heard of a Physiatrist? They treat the whole person not just a set of symptoms. Hope you get some good ideas from the rest of the folks who have TBI. Mark from Idaho is very knowledgeable about it. I hope that you heal, and can smell and taste again. ginnie
