Please don't listen to the idiot troll Awanda, she/he/it is hitting every thread on here talking complete BS.
Overcoming emotional eating and grazing is hard. I know that's something I've always struggled with too. I find distracting myself helps. I know this is going to sound weird, but night is my hardest time, so I've kinda "trained" my brain. Every night I brush my teeth and take a hot bath when I feel the urge to graze. Now, it's like a signal to my brain "oh it's bath and clean teeth time, we're done eating for the night". I know it sounds weird but it's worked.
I also find keep safe food around for when I just have to have something. I really like both dill pickles and cucumbers. Both are zero calories, so when I need something I grab one.
Hang in there.
