Hi Deb!
I just started the OOO yesterday, but I have been feeling full or satiated within the first few days of this WOL. It's probably the metformin for me, though. I've spent my whole adult life eating constantly. Even after a large meal, I'd browse the kitchen and eat until I was so stuffed I couldn't move, but never felt "full." I ate my way up to 255 at one point.
