I don't drink
If you tried Dry January or February and succeeded, well done. At the same time, just reading the posts on some of the relevant blogs it is clear that many people coped with a 'Dry' month purely on the basis they would be able to get 'hammered' when it was all over. That is the whole problem with trying to moderate your drinking, the thought of that next drink never escapes you. Dry Forever is so much easier because of that! Why not make that your commitment from now on?
