I was taking 200 mg of Trazadone a night and still only getting 3-4 hours of sleep often interrupted. I started having balance issues and blurry vision. It cleared up quickly. So it does affect our brain. Has any one tried cognitive behavioral therapy? My pc recommended it. They have tried max doses of four other drugs and nothing seems to work. I fall asleep ok just can’t stay asleep and I’m tired of getting up at 1 -2 every morning.
