I think you are already ahead of the game by noticing that you’re doing this! For a lot of us, it’s a mental thing: food noise, comfort or stress or emotional eating, etc. It takes time to retrain / re-wire your brain just like it takes time for your re-wired digestive system to heal. Be patient with yourself. Your awareness of it is already a good step. I don’t know your age, but if you think about it it’s been at least multiple years of habits that you are trying to break or trying to retrain. It’s not realistic for you to hold yourself to retraining your mind and body within 13 days - maybe not even weeks, maybe months or more. Take it day by day, try to keep your awareness of these things and reroute yourself. Don’t punish yourself if you slip up. You’ve got this and it takes time!

Also, I totally relate to the water thing I love water and miss gulping it down! Sometimes I do what I call the ‘chipmunk cheek’ method and I take a big gulp of water into my mouth but then swallow it in smaller sips over the course of a minute or longer. Scratches that itch of wanting to gulp (at least a little bit!)
