Eating too much sugar will just lead to more sugar cravings. This is a familiar addictive cycle that you would probably like to avoid. Instead, you can control these cravings and rebuild your health by eating regular meals that are rich in protein and nutrients. Some of the healthy meals that you might eat in a drug rehab include: Breakfast: Yogurt, omelet, or oatmeal Lunch: Chicken breast, deli sandwich, ham steak, or tacos Dinner: Salmon, pork chop, top sirloin, whole grain pasta, or chili – with vegetables and salad
