Second the thought..."you didn't waste 3 weeks.." Although it gives us drunks a reference point to see our accomplishments,helps us to put a geometric point on the calender of our sobriety...the number of days in a row you didn't drink matters less than the fight you put up when you fall eh?
3 weeks without is still three weeks without, if you fall, get back up and look forward to fighting the continuing fight. One day today, another tommorrow...don't drink today.
When we're not clouded with booze, we can deal with the underlying issues that trigger us to do the same. I can't get healthy unless I continue to fight the battle.
Peace today all.
