I wonder if anyone can give me info on this? Basically I do quite a lot of sports and my current inhaler doesn't seem to last me when I'm exercising and end up really tight chested and short of breath. I'm currently on ventolin and is fine when I'm just doing normal stuff but not when I'm exercising. I'm going to see asthma nurse next week but someone mentioned oxis to me. Just wondered if anyone has any experience with this?
