pain
"Aleve PM was wonderful in helping me sleep.  I had a lot of pain after a fall.  What I did not realize was that it was seriously affecting my brain function.  After a couple of night of taking Aleve PM, I could barely function at work.  For example, I needed to take notes at a meeting.  When I reviewed the notes the next day, some of the entries just did not make sense.  I then read an article that said that Aleve PM could cause a 'brain fog' in people over 60 (I'm 74).  After one night's sleep without Aleve (not a 'good' night's sleep) I noticed a huge improvement in my cognitive ability.  Anyway, I ended up tossing out the pills."
