inruins

I have a Military drug test coming up on thr 14th, I imagine it will be pretty extensive so I have a few questions....
I am 6'1 180lbs--not a lot of fat but not a lot of muscle.

The last time I smoked weed habitually was the 20th of august,
I was completely clean up until the 25th of october when I took one big hit. Got pretty stoned.
I smoked like 4 bowls of peyote out of a bong with a fairly well resinated bowl on the first of this month but no actual weed.

for the last week or so, I have been drinking about a gallon of water a day but minimal physical activity and not a very balanced diet (college food). Also, I have been taking a multi-vitamin with 50mg of niacin every day. I plan on doing this up until the UA. which is one week from wedsenday

Now, my question is...what are the odds of me passing, also, what else could I do to better those odds.

any adivce would be usefull...and spare me the "you shouldn't have smoked" reply cuz it already happened.

Thanks in advance
