You never know! I've known for years I had a problem, but didn't actively start trying to 'moderate' my drinking until a few months ago (found out baby on the way). Since that time, when I've over done it, I really try to make myself aware of the things that might have triggered me to go beyond moderation....
The realization that moderation doesn't work for me has led me to make the decision to quite entirely, so for me, it helps to be aware of those things that I might not even know are out there.... the insight is greatly appreciated!
