[Nyquil] sleep

I could feel the onset of a cold as I was getting ready for bed last night.  I always sleep terribly when I am sick, so just to make sure I slept soundly, I popped in a couple nyquil pills for good measure.  I failed to realize that it was 2am when I did this.  Waking up at 7:30am the next morning was awful.  I was so groggy and tired.  I'm assuming it was because I didn't allow for enough time to pass for the medicine to wear off.  I was "out of it" all day until I had time to take a 2 hour nap.  While I did feel better after that, I still lost 2 hours of doing something productive.  So, PLEASE don't make this same mistake.  Leave the recommended 8 hours to let the medicine work it's magic.
