Advair HFA and i am tired

I have been on Advair 500/50 for 3 years now. I have so many of the already mentioned symptoms which include a 40 lb. weight gain, the horrendous foot cramps that last about 15 minutes and can happen as often as they feel like it. I also have the heartburn, indegestion and very dry mouth. My doctor has never mentioned that my foot cramps were due to this medicine, he has tested everything to see why. I have decided no more!! I am tired of looking and feeling horrible, I feel like the goodyear blimp. Before I started taking this medicine I weighed in at 98 lbs for over 20 years Now I am at a whopping 147, can anyone tell me once you stop this medicine how fast does the weight and other symptoms go away?

I have been on advair for about 3 years. My two biggest problems are weight gain...lots! And the constant thick mucus in the back of my throat and in my lungs. I have never cleared my throat so much in my life. Even when I was just on singulair. Yes, my asthma is really under control, but at what future cost? I understand that having asthma attacks can damage lung function for sometimes as much as a year, if the attack is bad enough, but I am tired of how I look and my constant throat clearing and coughing. My father is also on Advair for his asthma, and he is the same way.
