I don't know where you live, but where I am, CBD is a big thing. It's supposed to be wonderful for anxiety and more natural than xanax, etc. (though I take the xanax myself). I'm considering looking into CBD for my anxiety. I'm awaiting my surgery (I don't even have a date yet), so I can't relate to the head hunger just yet. I have been going to bariatric support groups, and they suggest keeping your hands busy, walking and all of that. Or a rewards system that doesn't include food (i.e., you didn't snack, give your self a marble and once the jar is full, you can buy the shoes you've been eyeing).
