Ya it happens to me! Though lately I've only had staiva for forever, my inner glutton loves to bake, gorge, and veg. My girlfriend however reacts differently. She's always insta munchies and is naturally sedentary so she lounges after gorging. I have the overwhelming joy of rubbing her stuffed belly afterwords.
When I'm stoned, essentially always, my fat is what buzzes most. Reefer just makes me feel so fat!
And.... it makes me want to fatten constantly.
Pot is very compatible with fat. I self-test a lot. For reasons. When I'm growing fatter none of those happy metabolites are going anywhere so it takes me 3 months to "clean up". I used to clean up in a few weeks. Fat doesn't want to let that pot go.
I always bring my vape pen to the buffet and smoke in the bathroom between plates. It just gets me in the mood to completely stuff myself to capacity and then make me try a little bit more to stretch my stomach. I love nothing more than getting high and pigging out.
