I second not taking the xanax. I went to a quality concussion clinic and they told me to avoid it at all costs because it affects the brain like alcohol which is really not good. So sorry about your accident. It honestly sounds like you are better than you could be at only a month and a half or so out. So try to stay positive and make sure to take around 2000 Mg total EPA/DHA of omega 3 fish oil and b 12 vitamins at least. Read the vitamin thread. Also try resveratrol it helps with inflamation. Everything will be ok and you will improve. Also try melatonin for sleep and ask your dr about gabapentin for sleep. Its helped me. Good luck my friend.
