Severe Bronchitis Recovery Time

About 7 months ago I came down with a really bad case of bronchitis that wouldn't leave. Doctors put me on several rounds of antibiotics, but the same thing would always happen: I'd start getting better, but after about a week it would come back. I pretty much had constant violent coughing for about 4 or 5 months. I got to the point where I would cough violently, then have to use an inhaler because I would begin to wheeze and struggle for air. This progressively became more frequent, so my doctor put my on Advair for 1 month to get the inflammation from my lungs. Since then, I haven't needed to use my inhaler, but was told I had very mild asthma after a Pulmonary Function Test. My question is: I have not coughed since mid-March, and haven't used my inhaler. But, about 5 nights a week, I get a rattle in one of my lungs. After coughing up some phlegm, I am fine the rest of the day. It always occurs around 7 or 8 at night???? I also feel like many times taking a deep breath is difficult. I know my lungs aren't fully healed, but is this all normal??? How long should this take to heal ??? I'm a pretty healthy, 24 yr old female- very active, run 15 miles+ per week and don't smoke or drink (I used to smoke though very lightly for several years).
Anyone else had similar experiences????
