Hi there! I am 21 days today post-op as well! Woohoo for both of us! I have lost 23 lbs eating high-protein, low carb. I intro'd solids late last week and doing well...definately hear you on the sweating and nausea thing though if you eat too fast :S
I eat typically: low fat cottage cheese for break 1/2 c
soft egg whites for snack
sugar free applesauce -1/4 c
soup (broth based) for lunch..i usually can tolerate about a half cup
ground chicken meat ball or ground meat (i had meatloaf last night...woohoo...although, had about 4 bites lol)
mashed veg like squash puree, peas, etc...these are TOUGH so as much as I can handle. I want to start noshing on spinach pretty bad for the iron, going to try it today and try to combat this tiredness
shrimp-oh man, lovvvve shrimp and no issues with digestion...I find anything seasoned, overly salty, etc is what gets me.
Al lthe best!!!
