I'm going to get an MRI on my back on Sunday. From what I understand, I have to lay on a casket type container for about an hour. On Saturday, there is a crackin party and I was planning on getting fucked up. There are two things, if I get fucked up, i dont want to be in that container hung over and also, can they see if you've smoked our drank through the tests they give me? So do you suggest that I just dont drink or smoke at all or what? Please Help!
