I am 21/2 weeks post and on full liquids. I am having such a hard time getting protein shakes down primarily because of taste and aftertaste. I have been advised to have one for breakfast and one for lunch and all done by4pm. I have it down to about an hour per shake, then have to fill in liquida and then for dinner I have either soup, or mashed potatos (thinned with milk). I have no trouble to the soup or potatos. Anyone have ideas on getting protein shakes down easier?
