Argh, I can't concentrate on anything

Hey everybody,

Quit 12 days ago. It's been going great. I've saved a ton of money, feel better physically, don't even really crave cigarettes anymore, etc.

Anyway, problem is that I cannot concentrate at ALL. My work ethic has gone to complete crap, because I can stare at a problem for hours and not even know what it's asking.

I almost want to go out and buy a pack just so I can get my fucking work done! I don't even want to smoke, but my brain is completely consumed by clouds and fogginess. The way it's looking right now, there is absolutely no way I can get what I need to get done without staying up all night.

Sigh.

What can I do reddit? Any advice?
