I Currently Use Symbicort 80 Mg For The Last 3

I currently use symbicort 80 mg for the last 3 months and have been paying out of pocket since my insurance does not pay anything for it. ( I have a pulmonologist who is very pleased with the results) My internist today gave me a sample of 160 mg. and said to just take it once a day. I think 1 puff instead of 2 twice a day makes more sense.
