I'm excited for football too. I noticed since getting sober I enjoy the games just as much as when I was drinking, and I still yell obscenities at the referees from time to time. If your passionate about your team it'll still be a really fun experience. And instead of feeling the lone emotion of drunk you feel the highs and low points of the game. It's an emotional rollercoaster if you're a diehard fan like me but it makes it so much better that way.
