memory problems, insomnia symptoms, and twitchy feelings
in muscles are actually very characteristic of
narcolepsy with cataplexy.
In fact, often times, it's not "Bells Palsy," but cataplexy. Viruses and some vaccines (namely the H1N1) can actually precipitate this, but it can happen seemingly in random fashion, too.
It doesn't look the way you think it looks. Common misdiagnoses are depression, epilepsy, and migraines.
