One thing I know I am guilty of is unrealistic expectations. You just had 75% of your stomach removed! Your body is in shock; you are probably still feeling the effects of the anesthesia, you are eating around 400 calories a day, you were walking more than you are used to (muscles get tired!) and you are on an emotional roller coaster. I understand why they stress walking to get rid of the gas and get yourself moving, and hydrate and protein, but I feel like we also need to HEAL and be KIND to ourselves. This will pass.
