My doctor prescribed Advair last week and I am supposed to take one puff twice a day. I have done it for the past 3 days. Now I am afraid to continue because of the side effects you all mention. How long until you began to notice the weight gain/sleeplessness, etc.? I just lost 40lbs and it took a lot of hard work. I will not let this drug ruin that for me. (I don't have chronic asthma, I am just having trouble getting over a bout of bronchitis.) Thanks for any information you can offer.
