Hi Mes,
I used to shake a lot too...I can completely relate to the embarrassment. I also had panic attacks and extreme anxiety. Since I stopped drinking, everything has changed. No more shaking, panic attacks and I feel calm.
My advice is to pour out the wine and any other alcohol you have in your home. Go to the meeting sober and let your recovery begin. You won't regret the decision you've made!
Wishing you the best!
