Should You or Shouldn't You?

First I agree your Dr should be consulted/kept in the loop of what is going on as I don't believe this is normal.

You may want to start keeping track of when you feel sick..i.e journal your food/fluid intake if your not already doing so including how much of each thing your eating.  Then note afterwards if you get sick.  Try seeing if there is a trend on if its a certain food or quantity that is triggering it.  It may help you and your Dr figure out what is going on.

Good luck, I hope it gets better.
