For me I am kinda stuck at 25mg a night, and have been since my hell on earth episode begun late September last year. If I don't take it, even for a few nights in a row I get zero sleep. I would rather Sroquel in tiny dose than Stilnox or Benz's. Melatonin is like candy to me. All the CBT sleep routine does nothing. For now my brain is ***ked. However, in the past this has happened and suddenly, for no reasons I can explain, bam, I need no sleep aid. Our brains are all different.
