Hello. I m 42 years old, female. Out of nowhere, about 6 months ago, I have begun falling asleep, even while I am standing up! It seems to be just brief periods at a time. I have to admit, I am a very unhealthy person: 5 4 , 400 lbs, very stressed, suffer from PTSD, OCD & ANXIETY/PANIC DISORDERS. Smoker, severe back problems have caused me to gain 200 lbs over the past 4 years because I can t move well. Severe pain in back. No pain medicine has worked for me yet so now I just don t take anything at all. I have mild scoliosis and degenerative disk disease. For 222 years I have suffered from debilitating migraines and T.I.A. (Transcient Ischemic Attacks). There has been nomrecent change in my medication. I have been on these same medications for about 20 years taken daily: Indural ER 180mg, Paxil 120 mg, Imitrex 100mg and birth control pills...
