I have been taking Advair, Singular and a nose spray for 2 weeks with great results. However: when I was in fr a chek up I mentioned muscle cramps, I thought was unrelated but he immediately changes my prescription from ADvair and said it also ocassionally caused tiredness and sluggishness inthe morning. MY son prescribes Advair all day long and had never heard of the until I called him. He will bw watchful for this from now on. I feel a hundred times better this morning!
