Welcome, Ragurley!

This doesn't sound right. The surgery was a month and a half ago, and a few weeks ago nausea and vomiting started up for you. Those symptoms might be related to the surgery but then again they might have nothing whatever to do with it.

In any case, I would strongly urge you to consult a doctor about the nausea and vomiting. This shouldn't be happening, and even though it sounds as if you have had medical attention about it already, I think more medical attention is called for.
