I am three weeks post op. I started mushies last Friday. I am getting around 600 cal/day which includes a minimum of 40 g protein but I still don't have much energy. I am pretty much useless after 4pm. Is this normal? Does it get better or do you just get used to it?

I didn't experience any of that. I never lost energy & I am averaging 400 calories a day. I am anal about getting my 70-80 g protein & at least 64 oz fluids! Are you taking any vitamins?

I take a multi everyday. maybe I should increase my protein. What do you normally eat daily to get that much?

I was drinking the protein shakes or Isopure-Isopure has 40 g protein & no carbs but it is in a 20 oz bottle so it takes a bit to drink it. Pure Protein makes a Banana & a Strawberry that both have 35 g protein. I found them to be tasty. I haven't had any problem since the day after surgery getting my protein & water in, but now it looks like I may be allergic to the whey & finding a tasty alternative it very difficult.

I felt the same way until about 7 or 8 weeks out, no energy, I just felt crappy. It will get better, I promise you!
