Another Advair user here...
I've been on Advair for ~2 years now at the lowest dosage (100/50) and weigh the same as when I started, no increase in appetite. I have noticed increased hair loss, but that may be an aging-related thing (I'm 47) and the the hoarse voice that others mention (some days but not others). I rarely catch a cold, but that was the same pre-Advair. I do think it has helped my lung function/endurance for cycling and running, though my lung capacity (as measured by a peak flow meter) is still lower than I would like. It improved a little with Advair, but not as much as I'd hoped.
