Tonight day 2 no sleep. Took .5 mg ativan. Dozed off for an hour wide awake but very tired. Just took 5 mg ambien tired but no sleep. Help. will call psychiatrist in morning. Thought I would post again. Up at 4:30 for work at 6 am. Taking my zoloft before going to work has helped during day but by mid afternoon the shakes of being tired set in go to lunch in car to try taking nap, a no go. I am only on 12.5 Zoloft. How long insomnia last.
