Its not entirely an absurd question.
I would figure that outside of a lifestyle change, it can be prudent to prepare and deal with the realities of the Playa.
Me, I'm a six-pack a day kind of guy. That makes me pretty much an alcoholic.
This month, I make it a point to run dry weekends. Its generally good for me and I get ready for the booze free weekend drive to the Playa.
On the weekends I take vitamin A and B complex, milk thistle and folic acid to help clear out the liver.
I add lots of Omega 3 & 6 fatty acids via fish, walnuts, flax seed etc.
When I hit the Playa, I continue with foods that promote celular hydration. Usually its nasty foods like smoked oysters, kipper snack, sardines, herring etc. Don't know why but they taste great on Playa. Wouldn't eat that in the real world.
I'd say listen to your cravings. The desire to grab a jar of pickles and just drink the brine is telling you something. If you suddenly salivate when someone mentions smoked salmon, make sure you find some.
