Tip it away. Whatever is making you feel stressed won't be made any better for more than a few hours busy the booze. It'll just set you back, cause more problems, an make you feel badly about yourself. Play the tape forward past that first drink. Really think it through.
There are common triggers. Yiu can remember them by HALT. These are Hungry-Angry-Lonely-Tired. Which could you be at the moment? If yiu may be one of them (even if you don't feel it specifically) take action right away to alleviate that. Hungry? Eat. And drink plenty of water. Angry? Make the decision to forgive and let it go - your sobriety is more important than whatever you might want to drink at. Lonely? Phone a relative or friend, or get to an AA meeting or church or ANYTHING rather than drink. Call Samaritans or the AA hot line. All these things are there for a reason. Tired? Rest, even if you can't sleep. Take a relaxing bubble bath. Slouch in front of some cartoons. Snuggle.
Drinking is NOT the answer. Ditch that poison.
