I just quit smoking two weeks ago and found the toughest time for cravings was the first 3-4 days. After that, there were a lot of uncomfortable symptoms, but I welcomed them as detox, getting all the poison out of my body.

I'd suggest staying away from smokers for just those first few days, then get back out there with them. They are there. They will always be around and you will have to live in this world with them. My dearest friends are smokers. Check out my blog (http://curezone.com/blogs/f.asp?f=286). I've documented my progress, including my feelings around other smokers.

You're right: you did it before (14 years) and you CAN do it again.
