Should I Push It?

Hey gang

Once again I turn to you guys for your expertise. Yesterday I was on the go and grabbed a grilled chicken breast and a small order of green beans. I didn't get a chance to weigh the breast but it wasn't huge. Anyway, I ate half the breast and 2 spoonfuls of the green beans, I was ok then but about an hour later I came back and finished the other half with one more scoop of beans. This was my dinner and I tallied the calories nothing too high at all and loads of protein in the breast. My question is two fold. First I always UNDEREAT my sleeve big time and Im wondering should I test my sleeve to see when the restriction kicks in? Im always nervous that Im overeating so I eat really small portions and just stop after that. My other question is does a whole chicken breast in about an hour seem like a lot to you guys? Granted it did take an hour to finish both halves, but I would have thought I would have felt much fuller even a little discomfort, didn't feel like it was thanksgiving dinner full or anything.
