memory problems, insomnia symptoms, chronic pain, taste hallucinations, smell hallucinations, and
twitchy feelings in muscles are actually very characteristic of narcolepsy
with cataplexy, and it can be exacerbated by the hormone shifts that happen with menstrual cycles. In fact, often times, people don't have "Bells Palsy," but cataplexy. Viruses, and some vaccines (namely the H1N1) can actually precipitate this, but it can happen seemingly in random fashion, too.
