27 pounds in two months is great! I've only lost 16 pounds and I was banded January 24th. And like you, lost of my weight loss came from the liquid diet before the surgery.
Don't be disappointed. I felt no restriction at all after my first fill. However, after the second fill I immediately felt restriction and have begun (slowly), but nonetheless begun to lose weight.
I was banded in January...didn't really lose any weight until my most recent adjustment. However, now eating is miserable. I am constantly throwing up and have terrible acid reflux. Is this normal? Does it subside at some point? I don't want to "undue" the adjustment because its the first time I'm losing weight after having been banded. Anyone experience this as well and come through it?
