Bests & Worsts Reviews from Amazon

I DO NOT KNOW WHAT YOU ARE DOING TO FAIL BUT THIS PRODUCT WORKS!!! My appt was at 2PM - I drank 32oz water starting 10AM - then drank 32 oz of qcarbo32, grape (much better than other flavor) then drank ANOTHER 32 oz water. Starting testing myself at NOON and was NEGATIVE. took my test at 1:45 came home at 2PM and was still NEGATIVE. This is the SECOND time I have used this product. Buy Easy @ Home single drug screen test (10/box) for piece of mind - also sold on Amazon.
