....djdonee, I'm 35.... Just last year I was in your situation. I had the EXACT panic/anxiety issues that you are dealing with. It was 8 months before mine was completely gone. Now they did get less and less frequent as time went on, but I thought I would go crazy before they stopped. I thought I had perminant brain damage, and was gonna have to live with it for the rest of my life. It gets better just stick with it. I hit the gym hard over the last year and that has helped me as well.
..on another note, I broke down to the pressures of my family/friends (old drinking buddies) and had a few beers with them on Christmas day. I had no problem quitting after about 6 bud lights. Got up the next day, felt great.... life as usual.
...I was cooking dinner this evening and started feeling the weird dizzy waves, slight nausea, and sensations of hot and cold. Yup, it was the old panic attacks I remembered. They didn't bring me to my knees, but it reminded me of why I quit in the first place.
Hang in there!
