cough and nasal congestion
"Took first dose at 8:30 am and went to work. Definitely cleared me up so, as directed, took another dose at 12 hours (8:30 pm) and went to bed feeling tired. As medication took effect, I became restless and tossed and turned and found myself unable to sleep. 1:30 am and I'm learning of my mistake. Packaging should definitely be updated to disclose this fact. Works great to clear sinuses but I won't take again at night due to side effect of insomnia"
