I go to sleep at 10;pm after taking 50mg. TRAZADONE, I sleep for three or four hours and wake up. If I try to go to sleep again I will doze off for a few seconds and wake up short of breath. Each time I doze off I wake up. I'm up all night, and sometimes in the morning I can sleep for an hour if it lets me. I had bypass surgery four months ago. Can anyone relate to this? I also bloat. Stomach gets extended and breathing becomes difficult. It will go away, sometimes in a few minutes. I am 85 years old. The surgery was easy, but the problems they say are ssociated with it are taking their toll. Please reply.
