I have taken the Strip cleanser 3 times between 2000 and 2006 (Pepsi Bottling Group, Thrifty Car Rental, and FedEx) and have had success all 3 times. I got the kit at a local "smokeshop"...there are different kinds, I used the one with a small bag of pills and a small bottle of liquid. Followed the directions exactly. No bullshit.
