Mike;
FOr me, it "allows" me to sleep. It doesn't make me fall asleep.
If I awake during the night, I am able to fall back asleep.
I am able to take two 50 mg tablets if needed. I have only taken one, however. That's all I've ever needed.
Also, if I don't take it 10 hours before I want to get up, I'm groggy all the next day, like a hang over groggy, ya know.
I didn't have to wait weeks for it to build up in my system. It worked right away, but, then again, I was so tired....But, I take it only as needed, so, I don't think that's an issue.
Finally, Trazadone is a mild anti depressant with sedative properties. The usual dose is up to 150-200 mg/day, divided into three times a day.
Hope this helps.
