Yes. It just takes time for the body to adjust. By tomorrow it might have gone. I find it pops back now and again just to check if I am weak willed, What's really good is that now I recognise it and don't feel I have to respond. Oh. I am hungry. It will pass. More water. It's gone.
Weird really - having spent my life responding instantly to hunger I can now observe it almost from a distance and not respond.
Well today anyway! May not be as philosophical tomorrow.
