insomnia
"I've taken other prescription sleep medications in the past but they do tend to make your drowsy and have all sorts of side effects.  I suffer from rheumatoid arthritis and the pain stops me from sleeping.  I now take this at bedtime with a small dose prescribed codeine.  Between the painkillers and the "sleep" effect of the Tylenol, I truly can't believe how well I am sleeping!  Just be aware that this can really make you fall asleep fast so do be ready for bed.  I've spoken to four other people who have various pain problems and they all love this medication too."
