I suffered from nausea and vomiting which is now under good control. In the early days it was awful, and to begin with no one could figure out what was going on. Mayo Clinic were unable to help me, and all of my tests kept coming back normal.
I found a great physician in NC who has been able to get to the bottom of my issues (which turned out to be motility related). My doctor is an IBS specialist, Dr. Drossman (Chapelhilldoctors.com) – he is excellent. I highly recommend him and he will work with you over time to get to the bottom of things.
