I have the sour mouth, involuntary movements (hands, arms jerking) but the most troublesome and dangerous is the falling asleep without warning, anywhere and anytime. I have missed work because I crashed out in the staff lounge and couldn't get back to "alertness," and the worst is that big chunks of my days are GONE. Just GONE. It's as though I blank out and erase whatever part of the day is happening when the wave hits me. Some memories come back, slowly, and luckily I have patient friends who help me bring some memories back. I am Bipolar I, rapid cycling with mixed states thrown in. Lots of hallucinations, mostly auditory.
