The Super Bowl party I attended was no big deal at all. I walked in exhausted and with a cup of coffee and switched to water. There was tons of great food and snacks. There was plenty of alcohol too, but no one had more than one or two drinks. I totally was making a mountain out of a molehill in my mind leading up to the party. Probably everyone there realized that I had quit and it was no big deal.
Inc, I agree with your thoughts about coffee. I'm down to one cup or so a day, but with only four hours sleep last night, I will probably imbibe more today. For a couple of years, I had quit drinking coffee entirely and switched to tea, but I needed to switch back to drinking coffee again to deal with waking up each morning after heavy drinking.
My approach to caffeine is like my approach to all mind altering drugs. If one is good, two is better, and three is best. It's just the way we think.
Have a great day all!
