Gills symptoms and conditions

Been on Advair for 10 months, and have gained 20 lbs since then!! Also experience sharp head pains, foot & leg cramps, short term memory loss, irritability and mood swings, increased menstrual flow, slow healing of wounds, etc. Main concern is rapid weight gain! I went to my dr today to discuss...she claims to be unaware of any of these side effects being related to Advair....she can't imagine weight gain as Advair is a powder that goes into just the lungs. My mid section is where I have gained mostly. After reading all the boards on different websites, I am surprised to see how many are experiencing the same side effects with Advair, & I am convinced that it is the cause. I asked dr to prescribe something else, & she did...asmanex & serevent....haven't tried it yet...but I now read that asmanex is also linked to weight gain. I feel so frustrated that I can't rely on my dr for this, & feel like I have to fiure it all out on my own. I'm scared to continue with these meds but I need something to keep my mild asthma under control....everyday. Can anyone recommend anything to me? Should I switch to non-steroid? Any feedback on Singulaire somethin similar? Any information will be helpful. Thanks!
