Diagosed with obstructive sleep apnea and ADD. Been taking trazodone 50mg nightly for about the last year and a half, and it has pretty much became ineffective recently. Where I was averaging 7-9 hours sleep, I'm down to 4-6 and waking up numerous times during this time. I am also taking Adderall 20mg, once when I wake up, and 10mg about 4 hours later, and another 10 mg later, if needed, but seldom take the last one.
