Hang in there.
There is a lot of bad advice out there.
Cut the sugars and the carbs out. A lettuce salad, a lean protein, and broccoli is a healthy meal.
Drink all the diet sodas you want. Add lemon juice to make them drinkable. Coke zero, diet ginger ale, mountain dew, and diet Dr pepper and diet root beer are the closest to the real thing. It is laughable that people worry about artificial sweeteners. In your priority of worries artificial sweeteners should be down there with worrying about how to tell your boss you are quitting cuz you just won megamillions lol
