I don't drink alcohol and in my life I've only drank it twice when I was 15 (over 40 now). I made it through most of high school and all through college working in bars and nightclubs as a teetotaler. So I have alittle expreience with this and I can say without a doubt that it doesn't matter what you say, if someone is the type who is going to pressure you into drinking they will do it no matter what. Your excuses, whether they be that you don't drink or quit drinking, are seen as a challenge. Just another hurdle they need to jump to get you to conform.
