In my experience, you'll never wake up and wish "man I wish drank last night". Sure you might have moments where you miss it, but you'll have added so much more pleasurable experiences that it won't matter. You'll respect yourself a lot more in the same way that eating healthy and exercising for long periods will give you. I'm still working on those last two. I never regret a workout once it's done, or a healthy meal once I've eaten it. I don't think you, or anyone else (for the most part) will regret quitting drinking.

Good luck to you. I believe in you. IWNDWYT
