Should I Seek Another Medication for My Breathlessness?

Question

I am a victim of mild asthma and I have a doubt whether I am experiencing tension attacks every now and then. I find that when I have Albuterol, it does not provide me with full respite from my breathlessness. I informed this to my pulmonary doctor and he stated that usually this drug becomes effective within fifteen minutes and at times, it has more effectiveness than other times. I would like to know whether a Nebuliser will have better effect for me than this or are both just the same. I experience severe breathlessness when I drive my car and in hotels when I go out to eat. I feel that both tension and asthma are working hand in hand during these episodes. I would love to know whether there is anyone else in the same boat as mine and if so what is the solution to it. Please do get in touch with me if you can help me out as soon as possible.
