I think you could smoke, but I would try to get some exercise and do some sweating afterwards, and definitely drink lots of water and cranberry juice. Also, eat oatmeal; it actually helps remove fat from your body (where the "positive results" hangs out). Some folks think that's all BS, but it's always worked for me.

And last time they gave me flak about my piss being clear, I told them that if it ain't clear, that means you're not getting enough water (Doc told me that once). Once they made me piss again, but when I couldn't they MADE me drink water until I could - I said "okay!"
