alot of asthma sufferers have allergy problems that are aggravated when sleeping (i'm not one of them) for them, singulair would work better before going to bed...also, i'm not sure, but common side effects of drugs are inducing drowsiness, but i'm not sure if singulair does that or not...fortunately, i've never had any side effects to speak of with any of the long term drugs i'm on...
just a couple ideas...hope this helps
