Trying to stop drinking, first day no alcohol, how long will the anxiety last?

For the past 4-5 years, I’ve been a regular drinker. I usually went through a 5th 3 times a week or so. Here recently, due to extreme stress in my personal life, I have been drinking large amounts of alcohol almost everyday for the past 2-3 months. It got to the point to where most days I would drink before work, head to the liquor store on my lunch break, get 6 or so mini bottles & drink them on my break. Then drink more when I got home. I got tired of feeling like I had to do this just to do basic tasks some days just to function. I think my biggest realization was talking to a co worker who asked if I had been drinking & was wondering if everything was okay. Another thing, I realize how much danger I put myself and others in by being on the road like this. Yesterday I headed by the gas station to grab some beer, decided to put it back last minute and try my hand at not drinking. Thankfully, I don’t think I was so bad off to where I’ll face serious withdrawal symptoms. I do feel a tiny bit shaky, but my main concern is how extreme my anxiety is today. I’m just wondering, for those of you who have quit and dealt with anxiety like I am, how long did it take for you all to finally get over the anxiety?
