I would contact your GI again. Are you taking anything for the nausea? I use Zofran 8 mg every morning and Phenergan 25 mg every night. Both are good for the nausea, the Zofran doesn't cause drowsiness.
Before my resections, nausea usually was a sign that I had some narrowing going on in my intestinal tract. Definetly don't let this wait. You don't want things getting out of control.
