"was on ambien for almost 3 years because of insomnia due to overnight shift, fibromyalgia and depression that got really bad the last 5 months. started with 5 mg 2-3 days a week and it worked really fast. i would have to be in bed in 5 minutes after i took it otherwise i would start having weird hallucinations but that was a sign for me to jump in bed and i would sleep fine. but had to go up as i build up tolerance and the last couple of months had to take 2-3 10 mg pills and would wake up 2-3 hours later and needed to take another one to get more sleep, again i would only get 2 hours. obviously it stopped working so tonight i go the first time in about a year without it and so far i haven&#039;t been able to sleep in yet, been up for 26 hours."
