Drug Test Tomorow. I figure I'm just going to keep it in hot water until I need to go, then tape it around my leg right near my scrotum. I don't know if this will be enough, or too much. I figure, from the time the pee comes out of the water, it should be anywhere from 15 minutes to one hour. I'm going to get a thermometer too, just to make sure. If it's too hot, I'll just stick it in the toilet, but if it's too cold, I'm screwed. Any advice on keeping my substitution pee from 91-98 degrees, thank you.
