I went to my doctor a month ago because I've had difficulty being able to sleep soundly. I seem to wake up every 2 or 3 hours. She gave me a prescription for benzodiazepin. Taken 30 minutes before bedtime, and I took them as prescribed. My pills ran out and it was a week before I could see my Doctor again. In the week without the pills, it was living hell. Shakes, fast heartrate, sweating, confusion... Basically, in just a matter of 3 weeks on benzodiazepin, my body became addicted, thus the week withdrawl symptoms were brutal. I never thought I would ever become addicted to anything so quickly.. I was wrong. I'm completely off them now, but it was not a easy path.
