That sounds really scary. Hope your docs can help. I identified with your frog-jumped-out-of-his-tank-today story; for many years I felt compelled to think/ask "Guess what we did in French today?" when I hadn't had a French class for many years and we never did anything noteworthy when I did :-) But I kept the situation in the back of my head and worked on it like it was a "clue" and eventually figured a few things out about myself and what was happening in my life in the year(s) when I did have French and my wanting to get my stepmother's attention, etc. A lot of these things are symbolic I think and can be looked at like one does one's dreams. Any hurtful behavior like your Tylenol action needs to be stopped though, like one would want to stop sleep walking! Don't know how one does that.
