Welcome to the site Mark. We are glad to have you aboard. I will start of by warning you that one of the dips you take between now and March 1st maybe the "bad one".
With that said, I have to admit that your "I will stick to my plan" pledge is commendable. I'm not sure what the others will say about this, but I am going to take that pledge as an equal to posting roll in that I assume it will be your word. That's how this site works. You give your word, you keep your word. Without that this site is nothing. For the next month and a half, when you make that post, I will assume you are in the weaning process of the pre-mixed portions. If you vary from that by buying a can or bumming a dip you have broken your bond.
That being said, you may want to stay out of the groups until you have the tobacco completely kicked. It wouldn't be fair to the completely tobacco free for you to consider yourself their equal quite yet. If you need support until then, send me a PM and I will do my best to help you out. I'm sure there will be some more along shortly that will offer the same.
