i hardly ever got 8up, Epressed, too drained of mental resources after a night or week?end.
im sure my serotonin etc. was depleted, naturally, but the experience stuck with me, and was remembered as a fukin loved up blast. false emotions and all, yes, but its been done, and the night was yours, and your friends.
the negative effects you are feeling are just as sure to leave as the positive ones where to come. pop on some headphones, get comfortable and let your self just be.
dont be upset, or happy, listen to the music clear your mind and let a new mindscape play out before you.
i haven't had any MDxx in near ten years(!?!) and that was and is my choice; i had many many amazing experiences, and bad ones. thats only in the past now, but very meaningful to me still, and insightful no matter what.
