My Band surgeon had me strictly on the South Beach Diet. Are any of you on the same diet after RNY?

I am 4 months post RNY. Not so much a diet, but a lifestyle change. I do similar to South Beach I guess. Very high Protein and low carb. I probably average around 80-100 grams of protein per day and about 20 grams of carbs.

I am not on any particular diet, just a Protein first, vegetable and small amount of carbs with each meal. I eat 5-6 times per day. I drink at least 64oz of Water per day. My surgeon kept it very simple, and I like that. I have a 80 -100 gram per day protein goal. That's it. Following this plan, I eat around 1000-1200 cals per day by my calculations.

I was reading Alex's book about the RNY, and he mentions that it is extremely difficult to get in the total of ...64oz. water, 5-6 mini meals AND 80-100 cms. of protein. I'm baffled. I know, sip water all day. But how do you get THAT much protein in a meal that's a 1/4C-1/3C? I've heard it is best to eat more protein than drink it. Chicken has only so much protein. And post surgery, it's all another question. Am I to expect to drink 60-70+/- mg. Protein Shakes? Do they make them that high in protein? I know pre-op, the natural sugars in, say, banana's is ok in shakes but not after since RNYers don't do sugar. Right? I'm so confused as to how to meet my protein intake. I wanna do it right. Please share your "cocktail" of protein intake, pre and post op. Thank you in advance.
