It sounds very much like
narcolepsy. Recurrent "Bells Palsy," 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.
