Hi, I began taking Singulair for allergies, 2 week's ago. For ...

Wow. It never occurred to me back then, but I too was consistently waking up at exactly 4:30 every morning. At the time I was taking Singular and Serevant(?). I have had asthma most of my life and will tell you it stinks. During high school, I could barely walk home, but at one point it finally went away and I was able to run lapse around most of the kids in my class. Not until exposure to cats did the symptoms reappear years later. Last year my doctor put me on Advair. I will research this drug now. I don't like taking anything, not even Tynenol. I wish everyone better health.
