I have some close friends that have drinking problems and what I learned from their experiences:
1. If you're an alcoholic and think you can handle a single drink, you're lying to yourself. 2. It's honestly not worth it. Life is better than being stuck in a multi day binger. The physically effects are taxing on the body. 3. You'll always have those urges and that feeling of wanting to drink isn't as bad as the act of actually drinking and the damage the follows.
If you have those urges, attend AA (Alcoholics Anonymous) and refresh yourself on why you don't drink. I remember going out to dinner with a friend and the waiter knew my buddy. During the conversation he asked would I like something to drink. When I said no, he asked if I was a "friend of Bob". At first I had no clue what that meant and asked who was Bob. Later I found out he was referring to the founder of AA.
I personally don't drink around those that battle with drinking. I understand the struggle.
Stay sober. Reading about Tristan and it reminds me of all those people I lost as a child. I watched so many friends OD to heroin and other drugs.
