Dear RJY, congratulations on your sobertime. It's early days. Sobriety gets easier. Your body gets used to no alcohol. You will regain energy and enthusiasm. Stick with it. It gets better. Try viewing the wedding from the point of view, that you are getting well. You won't be sick that nite from the alcohol. You won't do anything to embarrass yourself. You will have no regrets the next day. Sobriety is the reward. Keep going dear.
