Still in a lot of pain is it normal to still fill the discomfort when I drink something

I haven't been having a appetite at all all I been doing is sipping liquids is that ok or normal not doing any food intake

I am 3 days post open as well and I have no appetite wither which is great by the way. Water, jello, and sugar free Popsicles have been my friend so far, broth not so much. I just don't like the smell or taste. No real discomfort except my stomach rumbling with gas that doesn't want to seem to come out the back side! Lol.... I woke up this morning and noticed something blood on my shirt from my large incision so I'm going in to see my Dr this afternoon. Other than that I feel better each day

Day 4 and I can't hold nothing down
