Stay sober and you will have the most beautiful morning of your life tomorrow, knowing you made it when the sun comes up and don’t have a pounding hangover. The anxiety will lessen every hour ( melatonin helped me sleep at night and green tea with additional green tea vitamin supplements helped during the day, as did fancy iced coffee). Do whatever you enjoy as long as it does not involve alcohol.
You may regret drinking, but you will never regret NOT drinking. Sending positivity and support to you!
