asthma
"I'm 28 & have asthma. I tried Singulair a few years ago, which helped my asthma & allergies. I recently began to have asthma flare ups again & started taking the generic. This time I am noticing side effects. I have frequent headaches, which may or may not be from the medicine, but could be from lack of sleep that I definitely attribute to this medicine. I get so exhausted  but can't fall asleep until sometimes 6 am, then walk around like a zombie the next day only to repeat the pattern. I am prone to depression but have not noticed it worsening. I am not a crier but now tear up over everything, happy or sad. I have sharp pain in my ears. Dry eyes. "
