Day 21 tomorrow for me as well. I too found it hard to get the first one in the morning out of my head.
To be honest, I've chipped a few times, but the last time I quit, I did the same and was off it for 3 years or so, before I started back up.

The extra cash is coming in handy too I had me a can a day problem going and usually paid 7-8 bucks a can. Do the math...... YIKES !!!

Good job to those kicking the habit
