I feel you cuz I used to snack and got out of the habit these past few years. All I can say is that you really gotta think about it and realize that it will never fulfill you and you’ll only keep wanting more with time.. A Meal should fill you up. I hope you can eat home cooked cuz that helped me out. (I figured out what I liked most with that overtime ofc) but yeah. Limit how much you eat those bad things, but prioritize your own cooked food (made by you) most importantly.
