insomnia
"I took trazadone for nearly 15 years to help me sleep and loved it.  I feel asleep within 30 minutes and didn't feel crumby the next day.  After all of that time I suddenly had a side effect that I couldn't stand and had to get off of it.  Every time I took it I suddenly felt completely congested and couldn't breath through my nose.  (This is a rare side effect listed with this medication).  My mouth would be so dry and sometimes I'd even wake up feeling like I was choking.  I'm so grateful it worked for so long and wish j could still take it.  I can't find that same rest with anything else I've been trying."
