This may sound odd but since my op in June I have not been sick at all which is fab so not complaining but there has been 3 occasions when my body really wanted to (2 food related and 1 illness) I was dry heaving and salivating etc but nothing came up. This was much more uncomfortable than had I just been sick send had it done with. I guess I'm just worried that anatomically I'm unable to be sick. Anyone else had this problem?
