Over my years here, I have read of many quits being lost due to alcohol. I will share words of wisdom from one of our community members to caution you not to drink alcohol when you are quitting smoking:
"All kidding aside, I TOTALLY agree with you on staying away from alcohol. I lost a previous quit when I drank alcohol after recently quitting. Alcohol is incredibly risky to a recently quit person because if there's even the smallest thought about smoking in the back of the brain, it just makes it to easy to cave!"
Just don't a quit is a terrible thing to lose!
