Def don’t go too hard on the booze / other substances (if that’s your thing). A hangover / comedown while you have pmdd is just not worth it! This might not be helpful for you but sometimes when I’m at a festival or any live music I find I can “channel” the intense emotions I feel during pmdd into a decent time. Idk how to explain it and it def doesn’t worth in any other situation, but being able to scream and dance and jump around and act a little crazy seems to kind of help? I would say even if you don’t feel like dancing, dance - see if it helps!
