A word of advice

Here it is: Do not take 12 hour non-drowsy sudafed (or the off brand) at 6:30 pm. It turns out, not only does it not make you drowsy, it makes it IMPOSSIBLE for you to fall asleep- despite your cold and being exhausted- for a full 12 hours... on the dot, actually. Which is particularly brutal if you have 13 hours before you need to get up for work. 'nuff said.
