I know what you're going through. I made it four days before I relapsed, and made myself really sick when I did. Downed a 750 of Vodka that night. Blacked out, and had a conversation with the (gf?) that I don't remember. Sure didn't help me feel any better, but like with W it strengthened my resolve.
Got right back on, and now I'm at day 7. Try to get there, I know you can. It feels A LOT different than day 3 or 4. Actually functioning and able to think today. Sleep is mostly back to normal. Very worth the effort!
Stop believing you're powerless! If a twenty-year hard-core everyday drinker like me can quit and stay quit... anyone can.
