nectar Protein drinks (23g of protein)! You can order a bunch of samples to try and see which flavor you like. My dietitian had recommended an unflavored whey protein from GNC and I had tried it long before my surgery. I couldn't stand the thing, I ganged the entire time and now just the smell of Protein powder makes me ill. I had panicked thinking I wouldn't be able to do the surgery because the protein was a must. I still can't stand the smell of the Protein Drinks but the taste of Crystal Sky from Nectar is great (tastes very fruity). You can mix it with crystal lite and throw in some ice cubes.. Its great chilled.
I order it from enjoyhealth.com. You might find one flavor you like (there are a ton of flavors).
unjury chicken broth was also a good one. Again couldn't stand the smell, but it really does taste like chicken Soup broth (they also have an unflavored that was ok, along with strawberry sorbet).
Hope that helps!
