That's not a lot of time. I gained weight at first, too. I craved sugar more than ever when I quit drinking. Remember, it's not about how much you eat, but about what you eat. I lost pounds by eating mostly salads (with no store bought dressing - olive oil and vinegar only), lean meats, and limited fresh fruit. All grains and processed foods out of the picture. Then I have to move more. Keep moving. You're sober. That will help your willpower.
