I see the appeal of microdosing, but to me it renders similar to the kick you might get out of rebelliously sipping a pocket-flask at work. You get the mental boost of "letting loose" while impaired just below the radar.
I always had sensitive skin. I stopped using products in my hair, then I stopped showering my head, then I stopped showering altogether. Now I shower about once a month, washing only parts between the legs daily. I am the most smelly after I shower, that sour sweaty smell. Incidentally I read that this is some kind of fad in Hollywood.
