Advair HFA and avail

WOW! I guess I will consider myself one of the lucky ones after reading all of these side effects posted here. Let me first say that I have tried many inhalers -- serevent, flovent, ventolin etc etc -- and the asthma kept getting worse. Then my doctor suggested Advair. I've been taking it for several years now. I knew that all medications have side effects and I read through the list carefully. The medicine was a Godsend! It helped me so much that I would have recommended it to most anyone. Recently, however, I've started having the occasional heart palpitations and recurring sinus infections. I'm beginning to wonder if it is time to move on to another drug. I'm in my early 30s and have been trying to conceive for a few years to no avail. I recently read that Advair can cause irregular cycles and now wonder if it is playing a part in my fertility struggles. Only other symptoms I have are tooth sensitivity and occasional leg cramps -- however, these existed prior to starting Advair; they might have become more prevalent but I don't believe Advair caused them.
I'd like to hear from anyone who is currently trying Asmanex...that might be my next drug.
