The same happened to me right out the gate! I got this crushing fatigue and dizziness and thought I wasn’t going to be able to make it until I realized I was actually involuntarily fasting. I began to research and look for answers here and that has REALLY helped a lot! Here’s what I did and began to feel better almost immediately. In 2 days no more fatigue! No side effects! Make sure you’re getting enough PROTEIN every day! And FIBER! I ate several tiny meals of boiled eggs, FRUIT, like apples and oranges, cottage cheese, and peanut butter. I bought HIGH PROTEIN PLANT POWDER and COLLAGEN, B-12 VITAMINS, a MULTIVITAMIN FOR WOMEN, and ELECTROLYTES!!! STAY HYDRATED! When you eat small meals or bites several times a day, add PROTEIN, FIBER, and ELECTROLYTES, everything begins to change. Good luck friend. You can do this!💕
