Flu headache relief
Most Useful Review
Used this to recover from H1N1 flu. Despite precautions, I caught H1N1 on November 3rd, with persistent symptoms. A friend included Emergen-C in a delivery, and I decided to try it. Remarkably, within an hour, I felt considerably better, which was the first time in weeks I felt awake. After consistently using it, my fatigue and sinus infection dissipated. Even my husband, initially sceptical, is now convinced of its efficacy.
