Post-op 4 days

Well it has been 4 days now and the pain is getting better came off my pain med. Saturday I think it was doing more harm than good.I seem to be taking in fluids pretty good but yesterday morning when I raised up to get out of the bed I had a very fast nausea and vomiting feeling and grabbed for the phernagren but was really to late I had nothing to come up just like dry heaves what causes this? It feels so good to take my showers . Anyone that can give me advise on getting protein please let me know the mixes are nasty. Thanks to all you all are so supportive and understanding. May God Bless and Keep All Safe.

I use unjury protein powder unflavored mixed with 8 ounces skim milk and chocolate or frecn vanilla low carb carnation instant breakfeast and some ice in the blender dosn't taste to bad Barb
