since my car accident I have had bad sleep. I suffered a brain contusion among other injuries and an mri showed i had a 3.4 cm cyst on the cerbelum in feburary 09. Bad sleep since dec 07. been on sleep meds helped some, sleep 3-4 hrs then up and back to sleep, but then been off meds for few months due to insurance problems, so been taking OTC sleep aids (dont do much of anything, but without something it is FAR worse). wondering if the brain injury caused the problem or anti depressants/migrain prevention meds are to blame? But sleep problems really came before the meds so i dont feel the meds are the major problem. opinions? help?
