For the longest time I have been having problems with anger over everything. I would yell at cups that I dropped in the floor, or my feet because I tripped, I mean I yelled at everything. I thought it was because I was physically exsuasted from taking care of my disabled husband. I finally mentioned it to my pdoc and found out the answer to my anger. I was having break through symptoms of my mania due to my lithium level was not at a theraputic dose. Well my pdoc is not good at making sure I get lithium levels done every so often. Actually if I don't feel right I have to ask her to do one. I know take it three times a day at 300 mg. My anger has gotten better. But now my blood pressure is dropping abnormally low. I don't know if this is from the lithium or from my cpap.
