Quick fix works. 2 oz gives you just enough. And read the the thread at the top of the forum for subbing and you should be fine...and as important as it is for you to have your stuff together as with temp and such...you need to watch your behavior too. Don't be all nervous acting....or they will know something is up. Go in like you pee in a cup for fun everyday.

Not sure if that was the answer you were looking for...but hope it helps some.
