I am 19 years old & I have been on a low dose of Advair for about a year & a half. It has done wonders for me. Weezing is a thing of the past. I forgot how constricting & uncomfortable I used to be. It makes my atheletic hobbies more exciting & less of a burden than before. Taking that first 6 foot sprint was a nightmare & regretful in the long "run". Now I'm vurtually worry free. I still keep an albuterol inhaler close just in case, but rarely use it except for when allergies act up. I know of no side effects thus far.
