"i have bi-polar ii. have suffered from depression, hypo-mania, and anxiety. one thing constant was difficulty sleeping. sometimes night after night. i would just lay there and my mind would race. i have been taking trazadone for a little over a year. 50mg-100 if needed. i&#039;ve taken as much as 100, but often 50 then another 25 if needed. it&#039;s the best sleep i have ever had. i sleep through the night. if i have to get up for the bathroom, i fall right back to sleep. if i take higher doses i do get some grogginess, occasional blurry vision, and joint ache. but getting good sleep is worth it and helps with my other bi-polar symptoms. these days i&#039;ve only been taking 50 but it  still works and side effects are fewer."
