Insomnia

I sometimes suffer from insomnia.  It's happened several times over the past couple of years.  I've went as long as 50 hrs with no sleep.  It's not that I don't feel tired.  I do!  a bone achingly tired that, prior to the first episode, I'd never felt before.  I've tried everything to get to sleep, from alcohol (don't judge) to benadryl to psychiatry and nothing has worked.  I haven't tried prescription sleep aids for two reasons: a) I've used ambien before and it didn't work and b) I really don't like the side effects of these meds.  Thanks but I'm chubby enough without sleep eating.  So tonight I'm going to do what I always do and hope it works.  Good night!
