ok, I found some Diazepam 10 MG, in the back of the medicine cabinet in my bathroom, it's from like 6 months ago, and there is only 2 gone, so I don't think anyone is using them, so me questions are... 1. do you think that I should use them, if yes how many should I take (the bottle says take 1/2 of a pill, right before the MRI, my mom got them because she always was freaking out before a MRI, because of the fact that you have to go into the closed in tube, and she needed the MRI so they gave her them), and do you have to break them up like with painkillers? 2. what are the effects like? 3. how long will it last. 4. do you think people will be able to tell I'm on them? 5. do you think it would be a good idea to take them right before school?
