"i have been taking this since it was prescribed in detox three years ago. it has worked wonders for me. i only take 1/4 of a 50 mg pill and sleep though the night. i don&#039;t take it on the weekends to avoid building a tolerance. sometimes if i am under stress, i will take a 1/2 pill. the only thing i notice is that i need to take it when i have at 7 hours to sleep or i may be groggy in the morning."
