Boo,

I would take a couple of the little red Sudafed pills. I've never had any trouble with a couple of Sudafed and one or two beers but that is me. I would be careful. Some of the liquid cold medicines like Vick's Nyquell are over 40 proof. They are already pre mixed cold medicine and alcohol. If you think you need the mixed drink while setting up try everything the night before the job. That way you can see how you will react to the Sudafed and the shot. Good luck!

Tom
