how many calories should I be getting

I'm 8 days poet op and getting my protien (80 to 100 grams daily) and water (64 oz). I am averiging 600 calories a day which feels a little low. What is the norm the first few weeks after surgery?

600 is a normal starting point.  Great job on getting your protein and water in!

Sounds like you're right on target. Nice work!

What is the easiest way to get the protein?

Darn---if you're able to get in all that protein and meet your fluid minimum---that's great. Lots of folks struggle with that the first few weeks.  I assume all that protein is coming from shakes?

I would check with your NUT/surgeon about how many cals you should have.

However, usually, they say not to worry too much about cals this early out. Many programs keep you at 600-800 cals throughout the losing phase. So 600 would be acceptable if you were following that program, obviously. In fact, seems a little high for 8 days but if you're using RTDs it's understandable to me.
 
I would stay the course.

 I feel like bowing to you, I am no where near getting in my protien.  I had my husband go out and get me atkins shakes tonight so that I can supplement starting tomorrow.  Now after reading the label I will need 4 of them to get enough protien as I can only eat a couple of teaspoons of anything right now, and when I do, I am not getting my fluids in! 
Good for you! I am also only getting about 300-500 calories a day right now... so you are doing GREAT!
