Glad to hear you made it to day 2, let it snowball from here on out. Every time you think about stopping for a six pack remind yourself of all the reasons you don't want to. Always think how you will no longer have that string of days without drinking again. How you hate the pain in your right side, the itchiness, the worry. Using more will not make worry less, I have read that you drink from the anxiety of the damage you are doing which doesn't make much sense. Think about it, why drink more to damage yourself more to ease the anxiety from damaging yourself?
Think of how much you hate this infliction every time you think fondly of it. Remember the worst of times, realize it will only get worse. Run these thoughts through your head every time you approach the store. Just don't stop to buy, don't look back, keep going home and enjoy a cozy night with your girl. Ponder all you have and all you can lose. When the next morning comes, pat yourself on the back, you made it another sober day. Before you know it you'll be months sober and getting healthy.
Now is the time, do it for your girl, do it for us, but mostly, do it for you.
