Cycles of growth

I go through these cycles every 6 to 8 months, lasting anywhere from a day or two to months. During these cycles, I get very turned on by food, weight gain stories, and overeating. I don't know what sets the cycles off. Sometimes I'm into a cycle a few days before I realize it is even happening. Previous cycles had ratcheted my weight up from 186 to 280 pounds. If I recall, I went from a 32-inch waist to a 50-inch waist in about a year two cycles. I managed to get a hold of myself, did keto for a year, and returned to 198 wearing size 34 jeans. I kept the cycles at bay for two years until recently.
