I was in a fog right before I quit which was one of the main reasons I was finally ready to quit. After that I had the anxiety, sweats and all the other nervous stuff but no more fog. You will get passed that panicky state soon, I did right around three weeks. Next will likely be the remorse for things you have done and missing your dead family member named Alcohol.
Hang in there, you will be feeling "Normal" before you know it. I recently passed two months and finally felt the psychological part of the addiction start to lift. It was right about the same amount of time that it took my body to be over cigarettes. If you can make it past that point you will be all smooth sailing.
The toughest part for all of us is abstinence for the rest of our lives. A new chapter I have only just begun myself.
Keep up the great effort and pretty soon it will all be down hill for you.
