Happens to me all the time...

When i feel like i am going to throw up he said maybe it is because i have to get something out.

When i get an eye twitch - he once said "hmmm....somthing you don't want to see?"

When my ears start ringing - yep, you guess it "something you don't want to hear?"

Also, lately my chest has been tightening up like i can't breathe while i am there and i've been getting headaches during session.

In general, i think i have strong physical reactions to what's going on - too bad I can't lose my appetite for a while...
