Hello Pooh Bear. I understand the expense of the advair disc. I had a talk with my doctor and he gave me a bag full of them as samples. I suggest you let your physician know and ask for samples.
As for stopping that would be a bad idea, just as the others say. Not sure what you don't like about it. It is helping you, though you may not feel it, by keeping the inflammation in your lungs from forming. Therefore you will not have frequent attacks of asthma.
Since you have either a cold or the flu, a talk with your Pulmonologist would help to sort this out. May well be a coincidence and has nothing to do with the disc.
Another source is to contact the manufacturer and see what they have for low income. Many companies have free product when low income applicants contact them. This may be your best source.
Please tell me what you don't like about this med. I used for a few months and had no problems except occasional dizzy feelings. So I took it sitting down and waited a few minutes.
Take care. Karen
