asthma, maintenance
"Compared to last year, a feel may grass pollen allergy far less in my airways this year. Before starting Singulair, I could get asthma attacks of just low amounts of grass pollen. Now, my tolerance has greatly improved. The same goes with my eyes. It took some weeks, but now I hardly need eye drops (i.e. Cromolyn) any more. This medicine has truly exceeded my expectations. 
Side effects were slight itching and drowsiness the first two weeks or so."
