I have been on Effexor-XR for 3 months for hot flashes and they are down from 16 a day to about 3-4 a day. Unfortunately, I am not sleeping. It takes me hours to fall asleep and then I awake at least twice an hour and have been averaging less than 5 hours of sleep per night, which is not nearly enough for me. What can I take as a sleep aid? I have tried Benedryl and over the counter sleep aids. Nothing has helped.
