Lemongrass: I think on the 7 panel they may test for valium, why dont you look up info to find out how long it stays in your system, I believe it is only for 2 days, but not 100% sure. Then just maybe hold them off for 2 days, tell them you have a previous dentist appointment already scheduled for one of them days, and see what they say about coming in for the test towards the end of the week. That will buy you some time to let it get out of your system. Good Luck.
