Salbuterol symptoms and conditions

I have been on Advair since Feb. of this year, I have had a lot of these side effects but didn't really realize it was from this med. At first I was told to take it 2x a day, reading the directions it says it has to be 12 hours exactly apart. My work schedule didn't allow that so I just took it 1x....Working 2 jobs I just thought when I couldn't sleep and was always tired, it was from working a lot. When I told the Dr. about not being able to sleep more than 4 hours, I was told since I was taking the meds 1x a day that wasn't it. After a bad cold and bronchitis I was told I had to take the Advair 2x a day, now i'm more tired than ever, still can't sleep and have a headache that won't go away even with migraine medicine. I'm even jittery and forgetful--kinda ditsy now and itchy off and on all day...After reading this blog site I see its not in my mind and i'm going to stop taking this med. I think i'm going to the health food store and find something natural.
