Advair HFA and inability

Glad I found this site. I've had perhaps a handful of serious asthma attacks in the last 15 years. However, at age 49, I've smoked since I was 11. Nov 24th, was told I probably have moderate emphysema. No more smoking for me. Was put on Advair 3 weeks prior when they thought I was only asthmatic. I've experienced hoarsness, and inability to sing, and I suspect some weight gain (already).

Question: Are there any side effects from stopping Advair? I wan't to quit right away.

Thanks
