Josh:
You've been through an amazing amount of stuff this weekend, and got through it sober... awesome!
For your body -- pick up something to get your electrolytes replaced. Maybe Gatorade, or if you have a bike shop or the like which carries Hammer Nutrition products, pick up some HEED -- or if they carry Cytomax products, pick up Cytomax -- similar to Gatorade, but they use different sugars, and have a better absorption rate than Gatorade -- but Gatorade will do....
For you mind -- find an AA meeting and go. YOu can share with other alcoholics, many who have been through similar situations as you, and you can begin to learn to live sober. You don't want to have to go through sobering up again, do you? Once is plenty for us....
Best of luck, hang in there and take it one day at a time...
