How did you take the initial plunge?

I (33M) have been drinking 6+beers every night for atleast 5 years now. I tell myself everyday, "tomorrow is the day I quit." Then, tomorrow comes and I'm in the store buying another 12 pack on my way hkme from work. It's become routine to come home from work and crack open a cold beer to unwind from the day, then that one beer becomes 6 or more. Just the other night I drank 12 beers. I didn't get drunk, I didn't even feel tipsy, just bloated and regretful. I want to stop so bad but its gotten to the point that when I wake up in the mornings I'm craving beer. I'm not sure if it's the taste, or the ritual, or what, but it seems I just can't gather up enough self control to put it down and get things under control..

What have you guys done to kick the habit of reaching for a cold one at the end of the day?
