Hi ghostgirl!
YaY you for making it through the weekend! I, too, used to cook and drink, especially on Sundays. I do what others have suggested and have a fancy alternative beverage. I like La Croix orange flavored sparkling water.
It took me a while to not miss drinking while cooking until I realized that the finished product was way better when I cook it sober. What used to happen when I was drinking is that I would sometimes not follow the directions, be too tipsy to make something come out right or just plain mess it up.
Now I follow the directions precisely and it almost always comes out right. Focus on your love of cooking and you will find a new way to enjoy it. Sober!
