Need help new to the sitee

Ive been smokin for a few years now, and as off recently ive been but on probation and drug conseling, i get drug tested by both :(

I'm about 6', 155lbs, with a average/fairly fast metabolism
For the last 3 or 4 days i have been taking a few pulls on blunts and bongs about 4 pulls each day

the weed was anywhere from mids to some legit headies

I might be scheduled to meet at corner house ( drug consling) on monday, there is chance that i could postpone the meeting till next monday which would be sweet but i dont want to risk it

regardless, i have a meeting with my PO on tuesday and i will probably be tested then.

I have used the dillution method before, and have found that 5 days clean and a gallon of water + vitamn 5 has worked well

I have not failed a drug test and I sure as hell dont want to start now.

Should i risk dillution again, even though i would only be clean for 2-3 days? Should i try substition? Probation is monitered and drug consling may be monitered as well?

I am on a pretty tight budget now so i could probably spend about 20 dollars at most in the following days
