You are not alone. At first I felt hungry constantly but I don't think it was for any reason other than the fact that eating is now a big hassle and because the sort of stuff you can/should/whatever eat is not available or really expensive or just not what you feel like. So you just don't bother. After a while I just got out of the habit of feeling hungry, or at least just started ignoring it, which I guess can also be bad as I have been told not to lose any more weight but I suspect I will. If I sit down and think hmm, am I hungry, yes I usually am but often it is not really practical to do anything about it so you don't. So you may find this goes away after a bit but make sure you don't end up losing loads of weight.
Short version, we are always hungry, well we're on a medical program that makes it really hard to eat and really restricts what we can eat, what would you expect.
