Mindless eater needs to STOP!?

I am a mindless eater. I wont even realize it until i am standing in front of the pantry eating! I go for the chips or gummy snacks or even chocolate things like reese cups! IT is so annoying but i never feel full EVER i could eat everything in the house and still be hungry! I try to distract myself but it never really works! I have even got pills to make you feel full. I NEED HELP!
