I lowered my dosage of prozac for a while cuz i was having heart palpitations and I didn't know what was causing it at the time - now I figure probably too much booze and sugar -I had some rum cakes - and next thing like within a week I was crazy depressed. It is very very hard to hear. It's like everything has to be absolutely quiet for me to be able to tell if I'm level headed or not. It's not easy. It's very tiring.
