In my younger days I used to sleep a lot less but that changed after a hospital prescription for antidepressants (I think), to help with a condition I was experiencing at the time. After that I starting sleeping a lot but the funny thing is that whenever I miss the drugs sleep eludes me either partially or completely for days. I once went without sleep for 5 days after missing the drugs. But I'm learning to cope with the situation. I hope you find ways you overcome your sleeping problems. Thanks for writing.
dang ye that doesn't sound great going that long without sleep
