I had RNY gastric bypass just recently. I don’t get the hungry sensation in my stomach ( you know growling and noises ) but my brain tells me to eat eat eat and I just ignore it or drink fluids. It is very much a mental issue, because I am so new to this process. I am measuring my food out and weighing it just to get in the habit of eating less for once I am further out. If I finish it, I finish it and if I don’t I don’t, but after 30 mins I discard it and I don’t drink anything while I eat. I agree with what the post above says in regards to actual hunger and mental hunger. Just do your best and talk your feelings. Remember why you did this in the first place. It is a very difficult journey, but just remind yourself everyday and push through. I hope things get better for you.
