"i started taking trazadone (100mg) 10 years ago. it worked like a charm for sleep. i&#039;d sleep a good 7 hours, and had no hang over effects. a few weeks ago it just stopped working. so my doctor raised the dose to 300mg. i feel so much better mentally. but, it&#039;s still not keeping me asleep. i go to sleep for about 2 hours then i&#039;m up once every hour. i miss my good sleep so much!"
