Nyquil is evil. I used to get sick all the time with sinus infections and it was the only thing that would help me sleep. Fast forward a few years and I get sick and need to sleep because we are getting up the next day at 3:00 a.m. for a flight to Europe. It worked opposite. I was so wide awake I couldn't believe it. I guess that is the end of "Baptist Booze" for me.
