don't rush it, there are reasons. I thought I was feeling great just started purses just 2 weeks out, surgery was Feb 18 th RNY. Thought last night I would try a couple of small shrimp with my refrained beans, BAD CHOICE in pain all night ,thought I was having a heart attack. I'm having trouble getting in all my protein and fluids, so I though it would be ok for some protein, not easily digested no matter how much you chew, lesson learned, I'm trying two premier protein shakes breakfast, lunch, two snack fit Greek yogurt with 1 scoop unflavored protein, jello, Popsicle, soup w/ 1 scoop unflavored protein and as much water as I can possibly take, I always feel full, just head hungry. Let alone all the supplement...., I'm also tying to log everything on a really cool appt "lose it" feel better. Spirits go up, weight goes down
