This site has been very good for me. I was on Advair for about 6 weeks and had a sinus infection that would not go away. constant head aches, hand and joint aches, stomach problems, tired all the time and vision problems. I tried everything to get rid of these problems with no success. Then I decided to read the side effects in the Advair package. I stopped taking Advair that day and within three days was back to normal again. I stayed of Advair for 10 days then started again. Within 3 days all the side effects were returning. I didn't experience a weight gain but I have been going to Weight Watchers but have only been loosing about 1/2 lb per week. The week I quit taking Advair I lost 5 lbs. I was breathing better than I have in years but the side effects are just not worth it to me.
