When I worked in a preschool, I was sick for one year straight. At the time, unknown to me, I had developed a need for a medication like Advair to prevent infections from going to my lungs. Also, my calorie intake was too low which lowered my immunity. So now when I get sick, I immediately start Advair and get better quickly. Allergies/asthma were causing me to get repeatedly ill and now with appropriate management, I get ill maybe 1-2 times per year at most!
Also, at the time when I was getting sick for a year straight, I tried all the natural support and remedies out there to no avail, including Elderberry!
