As an older person who quit drinking quite a while back, I know that a lot of people dont drink and for a lot of different reasons, today it is much easier to go out and not drink.
If you ever feel the need to go to AA, you will find a lot of young wonderful people who are having a great time living it up without alcohol or drugs. I went to AA at 18 years of age 35 years ago and back then I was the odd one...after a while I thought I could not be an alcoholic, one of the reasons being that older people told me I had not drank enough....I proceeded to go back out for another 25 years and all I can say is I wasted a lot of years...The thinking has since changed and it has saved a lot of lives from being ruined.
Do what is right for you and Justfloating's post has great ideas.
Be good to yourself
