I have also been prescribed Klonopin, taking 1 mg a night, to try and get some sleep, but unfortunately my body still decides when it wants to go to sleep. I have found the same problem sleeping as Mark describes...I typically don't fall asleep until around 3 or 4 and I am up by 8 am no matter what, and during that time I still sleep very lightly and wake up at least once an hour abruptly. Usually after a week or so of only sleeping a few hours a night my body finally "crashes" and I get around 6 hours of somewhat uninterrupted sleep. I also want to thank Mark for the education on the half life of this sleeping aid. I am definitely going to discuss this with my doctor.
