Hi Doctor, I Have Been An Asthma Patient Since I

Hi doctor, I have been an asthma patient since I was in three months. Now I am using beclomethasone dipropionate and levsalbutamol sulphate rotacaps. Physician suggested me to use it for three months regularly. But I stopped using it after two days. Becouse I got releaved from breathlessness after first usage itself. I have learned that it has not major sideffects. I'm taking it whenever I feel breathless. I want to know if it has any warning about the quantity of usage? How can I understand that my breathlessnessans asthma is under control? Thank you.
