Diet is essential. No caffeine or stimulants for they can bring on panic attacks and chest pain. Learn what your body tells you about foods. Sugar is a stimulant. Water is vital to daily life. At least 70 oz, though you need to regulate according to what you are doing. Protein helps the body utilize carbohydrates and your energy will last longer. I dislike meat, but as a protein, it works best for me. I eat only a little and it does me great for sustaining my energy. Fats should be avoided. Salt is good for an MVPS patient for it holds fluid. MVPS patients have low blood levels and thus must drink water and use salt to keep those levels up. Vitamins have been helpful for me. As one ages, doctors suggest to take the vitamins individually rather than in one tablet. Minerals are what many MVPS patients are lacking. Take those separately as well. Remember not to overdoes on zinc and potassium.
