I agree that you should stay in close contact with your Dr.
Two things to consider:
Try putting fresh pepperment leaves in your water. I was given that advice 5 weeks out and it made a huge difference for me. Since it is fall i suggest you find dried leaves but it really foes help.
Second. Get of those protein bullets they sell at GNC as they pack 40 grams of protein in a small amount of liquid. Pour it over ice. Its not bad.
I hope this helps. It really was great advice for me when i needed it. Also GNC has some good tasting shakes but try to get sample packs because you dont yet know what tastes you can tolerate. I wish you success!
