Don't be nervous! Get ready for hell, yes it is going to suck and that is why the vets call this phase you are about to enter "the suck".. Embrace this pain, try to enjoy it, and do your best to remember it in detail. It will be a reminder of what you never want to do again and you can see just how much you were poisoning yourself. Make sure you Read read and then read some more on this site. Start with the welcome center. Post roll first thing every morning and keep your word not to use nicotine in any form. Develop a support group and dig in! It gets better!!!!! I will quit with you every minute, every hour, of every day man. Now go post roll, you will be posting in October.
