OMG yes. I think I've only thrown up a handfull of times too! Once when I was about 16 on our steps going up stairs. Again when I was 27 (me, my hubby and 18mth old at the time all had it together. I will never forget that!) Once after my colonoscopy age 33. The demerol made me do it. Of course I was so drugged that I didn't care. Then again at age 34. My neighbor and I had gotten it the same day. It was really weird. We had all been out at a club the night before. 6 of us and only Howard and I got it.... But yes, I completely hold it back until I can not anymore. I'm emetephobic big time.
Casey, I worry obsessiveley just like you when my kids get it. I worry for like 3 days straight til I feel I'm out of the woods. It's horrible. So I can TOTALLY relate to the shaking like a leaf in worry. You are not alone. Trust me!
