Sometimes I have it and sometimes I don't. It all depends on how much time I have between when I see the deer and when I have to shoot and how much anticipation has built up. I really can't point my finger on what actually triggers it and what doesn't. My first deer was like . . . Yeah, I shot it and no fever at all, but then other times, I can't stop the shaking and the heart pounding. First bow deer last year, it was my knee that wouldn't stop shaking, no fast heart pounding or anything like that, just a knee that would't stop shaking. But, breath in through your nose and out through your mouth to calm yourself down.
