Hey! This is a medical mission? I vote NO DON'T GO! What, on the other hand, you make a medication error, or a procedural error due to intoxication or detoxing. Sounds dangerous to the people? You are trying to help on the mission, really not far to them or yourself. Stay home get well, I'm sure there will be more missions in your future once you are clean and sober for awhile. Why don't you think of the ones you serve, what would they vote???
Just a thought, hugs and positive thoughts, Twofish
