I have been on Trazadone since 07 and on the same dosage (100 mg) and for the past two weeks I have had an inability to get to sleep after taking it. I lay awake until 1-something in the morning and even tried taking it earlier to see if timing made any difference and it didn't. I don't know what else to do. I'm wondering if a higher dosage would work? I used to be ready to fall asleep half hour after taking it.
