Advair HFA and controllable

I am a 55 yr old female that has battled with asthma my whole life. In the more recent years, it seems to be more related to allergies, than the earlier years when I was more affected by temp changes and activity. I have used a form of albuterol in inhalers for years to control it. About 5 years ago my doctor put me on Serevent and Flovent. Last year he changed me to Advair saying it was the combo of the two of them. I have gained a lot of upper body weight in the last 5 years. I have never had a weight problem until now and can't seem to lose it. I have also developed high blood pressure and have to take meds for that and for "water weight", and joint pain and have to take meds for that. I stumbled onto this forum and it has been a real eye opener. I realize that some of this is due to my age and body changes but I now wonder how much has to do with the medications, particularly Advair. I wonder if I can drop the weight - and therefore lower my blood pressure and cholesterol and maybe lessen my joint pain if I stop the Advair? Has anyone experienced anything like this. My asthma was pretty controllable prior to Advair - Thanks for any info you may have.
