A stronger immune system is the goal in making you more bullet proof to illness. Sugar lowers immunity immediately, and grains are high in that, so eating a true gluten free diet and no processed foods should help. Don't use over the counter medications. They interfere and do more harm then good, and make your liver work harder. Eat home made chicken soup, boil carrots, celery, onions and eat them with the broth, breathe steam in over a cup of hot water, stay well hydrated, and rest. Hope you feel better.
