What you describe sounds like asthma. Asthma is a very treatable disease. A person can lead a perfectly normal life with asthma and it will not damage your lungs in a permanent way. The puffer will help you to breathe easier and is not at all addictive.
Good luck.
I'm not a doctor, so what I'm going to write is of only my personal opinion.
You should see an allergest doctor who will give you tests to see if you're allergic to anything.i.e. dust,grass,trees,just about anything including food. If you are allergic, then the doctor will probably give you allergy shots. I get those and it works for me. You may have asthma and the puffer is not doing it's job too well. There are other and different things to take to control it. If I were you, I would seek out another doctor (allergest) as soon as possible. Having it difficult to breath is very serious. There are medications. If your still having problems, then go to another doctor and another one until you feel you have found the doctor that knows what he's doing and you feel he is helping you.
Your puffer is not addictive to my knowlege. I don't know what medication is in your puffer, so I can't be too sure. I know that I am not addicted to mine. Ask your doctor.
Feel better.
