Hi Candybear,
I don't know much about being bi-polar but I can tell you that caffeine effects me big time.
Watch out for Excederine and Midol and any other pain relieving medicines, they have caffeine in them, too.
You can switch to carob instead of having chocolate. It may be harder to find but it beats feeling all spazzed out on caffeine.
Hope you're doing well in your own apartment. (yippeee!)
