I have been having wheezing since the age of 2. And now I am 17 years. I used to take Montec LC for years to get rid of it. I used to take the medicine almost everyday. Now it doesn't seem to quite work on me. I have been taking steam for 3 months and changed my tablet which has reduced from everyday to once in 4-5 days. What do I need to do to get rid of this? How long will it take?
