Wouldn’t recommend it. Mdma use can increase chances of getting rhabdomyalsis. So can dry fasting. You need to be sure you reach a point of full hydration for a while before you dehydrate your body again.
I think it could help you detox quicker, question is if you really want that. Since I am guessing the normal detox is bad enough, faster usually means more intense (worse symtoms) but in a shorter time. Well kinda exactly what faster means yeah :P
I would honestly be a bit scared myself since brain-related detoxing can create really scary symtoms. Not that I think it would be lethal, but scary.
how many mg did u have? i have noticed i am more recovered when dry fasting 24 hours the following morning after a session. if i don’t fast it takes abt two weeks to get similar recovery. if you’re having those special headaches a longer dry fast and applying ice packs on the skull always solves that issue. intentional nose breathing and dr. joe dispenza breathing technique also helps
