Hey man, here is the one thing I want you to hear right now! I HAVE BEEN IN YOUR SHOES! Listen to the guys on this site, in fact we have all been in your shoes. We know what you are feeling, seeing, thinking, experiencing. You are right in the fog. This is your body's reaction to your quit. It sucks, but it does get better - trust us.
The amazing thing about my quit is that the fog you are experiencing is the WORST part of it. But it fades away over time. Some folks experience this for just a few days, mine lasted quite a while longer - about a month.
PM me if you need to. Get on here and bitch, whine, complain. Write down in your intro what you are experiencing. Then, keep on quitting. In no time, you will be 50 days in and feeling like a champ!
Hang in there. Keep yourself busy. Just embrace the fog for what it is. I like to explain it like this: It is one long kick in the balls. The point is, just suck it up because it goes away. And, I hope that you never forget what it feels like because hey, do you want to get kicked in the balls?
I am here with you. I am 60 some days into my quit. Like I said, I have been in your shoes and I am right here with you. If I can do this, you sure as hell can too. I am proud to quit with you.
