Just focus on what's best for you. I'm 101 days without the booze, and I've been around it nearly every single day of that time. I'm a bartender/server, so not only do I see alcohol all day, I physically handle it, spill it on myself, smell it...but don't drink it. And sometimes it helps for me to see people drink and make fools of themselves, 'cause I think to myself, "Man, I'm glad I'm not like that anymore."
This may sound too simplistic, but I like to keep things as simple as possible. Alcohol + Me = Bad Things. Notice, that equation contains "Me," not "Everyone." Alcohol doesn't affect everyone the same way. The way I look at it, if I were diabetic, I could still be around people eating candy and drinking sodas, but it's not a good idea for me to indulge. Same way I feel about my alcoholism.
