Harlee,
What you are feeling is completely normal. What I have found (and a good number of quitters have agreed with) is the mental withdrawal is by far worse than the physical. You see, even though your bloodstream is now nicotine free, over the period you were actively using, your brain built up hundreds of thousands of dopamine receptors. The irritability, rage, anxiety, depression, ALL of those intense emotions you are feeling now are the result of your brain rewiring itself to shut them down. That process takes time.....lots of it. Hang in there; it DOES get better. Slowly at first, you'll have glimpses of clarity and light where colors are brighter, smells are fresher, tastes are fuller....the glimpses will be brief at first, but over time will become longer and come closer together. It took me about two months before I had my first "glimpse" and it was a full nine months to a year before my brain had recovered from the process.
But it DOES get so much better.....you just have to continue to do this ODAAT.
My advice to you right now is to become as engaged with this site and with your quit group as your schedule will allow. If you haven't already, trade digits with them. Build relationships and your web of accountability to the point where if you don't show up by a certain time of day (noticed you were a late poster, and hope that you're a third shifter....but that's another discussion), they will come looking for you. Over time, you will begin to view them as an extended family. Trust me, you get so much more out of these relationships than just a dip-free life; you become part of the brother/sisterhood.
Quit on, young lady. With you today.
