I'm currently right slap bang in the middle of this too. Part of the purpose (for me at least) of getting the sleeve is that it forces me to get through this period rather than cave in, which is what I've always done previously. If I were to try and overeat, or even just eat too quickly or eat the wrong things, it gets pretty painful right now. It's a pretty brutal approach, but given that I have tried and failed for 12+ years it really was the only option left.
Interestingly, whilst I no longer physically feel hungry (it's impossible too because my body no longer generates that hormone), psychologically my brain is just screaming "EAT ALL THE THINGS". Really hope it doesn't take too long to get past that. At least in about a month I can get back to eating a full spread of things and without them having to be mushed up, that will certainly help on the mental side.
