All those 'detox' things aren't worth it in my opinion. They work only by diluting your system (and maybe replacing salts etc) along with maybe being a diuretic too. You can't 'detox' your fat cells! Can only dilute your pee!
Anyways, yeah, first morning pee is bad, middle stream pee is the best option (I guess)...Red meat, vit B, why not right..
Far as them watching goes - I have a friend who worked at Best Buy a couple years back. He just told me they WATCHED HIM! Was at "Quest Diagnostics" to have the actual test done. I can't believe they actually watched his dick at that place, crazy. I was thinking most pre employments by and large you didn't have to worry about that, but apparently that isn't something you can even count on. BEST BUY!! Are you kidding!
Thanks for the stories everyone, it always helps to get some firsthand knowledge on this BS!
They are not going to be watching you for a civilian job, maybe your friend did something to them which made them believe he was planning to substitute a sample...or he is talking out of his ass. If anything tell them you have a shy bladder, but personally been to quest out here and I was in a bathroom alone.
