DR elmore - Coldeeze only really seems to "work" if you take it at the first sign of a cold. It's also not meant a "cure", but just something that may help the cold go faster through your system. Next time, just stick to good ole Vitamin C and plenty of rest. -Of course, if you did actually have a cold, well... And there's been a lot of the "creeping crud" going around lately, so... Hope you're clear-headed and clear-chested soon. ~~~~~~~~~~~~
