My heart races when I'm hypo/manic, and I tend to lose my appetite. I'm too active or preoccupied to even think about food. When paranoia or that unsettling feeling I get when manic or have dysphoric mania sets in, I get a pit in my stomach. It's not uncommon for me to get shaky. There's sort of a buzzing in my head and noises are much louder than usual during those times. All my senses are heightened.
