I take a pretty hefty dose of Lithium daily. My once near-perfect memory is now a shambles. I have trouble remembering what words mean sometimes, or sometimes what store I've meant to go to as I enter a parking lot. I lose the car all the time, and will forget a thought in a second. It's not that it's going into a grinder or something, though. I tend to be able to remember quite a bit of things about a week or two after the fact. Things I had forgotten come back, which cause some odd moments if it was a point I was trying to make last week, which I say aloud as if in the conversation still. Needless to say, it's tres bizarre. I'm taking ritalin to try to counter it, and it helps some. I'm wondering if anyone knows what is physically occurring during this whole process. Should I be worried about long term effects? Anything else I can do to fight it?
