Question on best Protein powder

I'm trying to get together things I will be eating after surgery. What is the best protein powder to get? What about drinks and protein shakes.Any suggestions on which taste the best? Like everything else I know some taste horrible and I'm unsure about what I need to stock up on. Thanks for all your help

I used HMR shakes that I purchased from my doctor. They are good, especially the chocolate! Amy 

My post-op papers suggested Promod or Carnation Instant Breakfast (sugar free).  I was supposed to start protein powder yesterday but I haven't because I just don't have the money to buy anything else.  But I will get the carnation instant breakfast later this week and try that.  I will let you know how it goes.  I don't know if you can have the HMR shakes post-op, I was never told that I could.
