I use nitrazipam, you can only use it 2 or 3 nights a week & expect it to keep working though. I tend to use it only once or twice a week to alow myself to get some decent rest. I've tried many different drugs over the years & find most stop working if you take them all the time & hangovers/side affects can be rough. The nitrazipam for me has least side affects & no hangover.
