Adderall, and drug tests.

Let me start this post off saying i know there's already a post similar to this one, but i have different circumstances. Now let me fill you in on my situation, I'm 3 months deep into probation (first run in with the law) and a requirement for my probation is i complete a drug program. I go every Monday, Tuesday, and Thursday, and they test every day. I took a 30mg xr earlier tonight, and i have a test tomorrow. i know i'm already potentially fucked. I have a high metabloism, and stimualts are known for leaving your system quickly. since i have all this energy to blow, would spending the night working out, and drinking excessive amounts of water help dilute, possibly even rid my system of this? Any and all thoughts/comments/questions are welcome, and highly appreciated.
