Here is my best advice on the matter of deductibles: just count off on your fingers all the items that you suspect might be deductible - and then forget them, because they aren't.
Now don't say you can't swear off drinking; it's easy. I've done it a thousand times.
It's quite true I'm not drinking anymore; however, I'm not drinking any less either.
Say anything that you like about me except that I drink water.
I drink with impunity...or anyone else who invites me.
I don't believe in dining on an empty stomach.
