I have asthma, and every time I see my allergist, she has me fill out the Asthma Control Test:
It's pretty widely used, and it helps ascertain whether or not a person's asthma is under control. It might be a helpful tool for you. I agree with achievinggrace, there are a lot of medications out there that can be prescribed to help manage asthma, from long acting beta agonists (similar to ventolin, but longer acting), to inhaled corticosteroids, to antihistamines, to anticholinergics (which help dry things up).
I'm not a doctor, but it seems to me that using your rescue inhaler that frequently might mean that your asthma isn't well controlled. I know my doctor would adjust my meds if I were using my albuterol that frequently. But we are all different, and your doctor should be able to help you figure out what's best for you.
