Keep yourself occupied, Chris. Go to a movie theatre that doesn't sell alcohol; enjoy the movie (or two). Don't go near a liquor store, bar, or other establishment that sells alcohol; stay away from drinking friends.
Urges and cravings can be powerful but they can be overcome; they don't last forever.
Stay close to us; lean on us.
Be strong; 90 days is great; you'll feel great going to bed sober and even better waking-up hangover-free.
