My RNY was 12-12-08.  My favorite protein drinks are Biochem vanilla, and Isopure (powder) Organe banana mango.  I use lactose free fat free milk (there are more than one brand.)  Have you tried samples from Nashua Nutrition (single packs) or the sampler from Bariatric Eating?  I also like Worldwide vanilla or banana canned.  You can add crystal light for flavors, or the sugar free flavored syrups too. 
I eat the light and fit carb control yogurts.  I've juiced some leaf lettuce or parsley with carrots.  I make tuna salad: tuna in water, chopped celery (fine) and a little light mayo.  I love shrimp with shrimp sauce.  I use frontera salsa with corn and poblano chile to moisten chicken or fish.  Also lemon juice with basil. 
I eat different things than my family... my timing doesn't always coincide with their meal times anyway. 
Hope this helps a little. 

I honestly think that I haven't been getting enough protein, calories or water in.  Some days I do really good on one of those things but never all together.  And around TOM, I get really munchy so I manage to eat a lot more.  But after, i am back to eating maybe breakfast and dinner or maybe dinner and a protein shake.  And water is still a challenge.  I sometimes manage 5cups.  Today I'm at 5 but I got a lot more protein than I usually get.

yeah..I was stalled for like 2 weeeks...thennot for a week and then stalled again for a week and a half..now that I am forcing myself to eat a little more I am actually loosing...I think my body was not getting enough calories or nutrients...when I started working out I gained back like 5lbs...I was told by a million people oh well its just muscle...I was so sick of hearing it i just stopped telling people..lol....Sorry for your 2 lb gain...i know how discouraging it can be...I think it could be water retention too...not sure though...

I've vowed to stay off the scale from 2/1 -2/28. So far so good.  Am looking forward to a nice drop by month end. I'm sick of not seeing losses, drives me nuts!  BUT!  I've lost 2-3 pant sizes and 2 ring sizes. Just bought myself a new (fake) pretty to get me until goal when I can have my wedding rings re-sized.

I don't know if I'm craving the carbonation or just the taste of it...
