Nyquil no more

 In the past, whenever I did get sick (once every 2-3 years), what I would look forward to is popping some Nyquil and feeling real good before passing out in bed.  Fast forward to now, and a few days ago I got the chance to take some Nyquil gel caps.  Being that it's been a while since last having some, I figured I would go with just half the recommended dosage, just 1 capsule.  I woke up the next morning with swollen, sensitive, red lips and my tongue was the same way too.  I've had that reaction to a sleep aid pill before so I knew what happened.  I went over to the box and looked at the active ingredients.  Sure enough the culprit, doxylamine succinate was on the list.  I thought Nyquil used a different ingredient before but it doesn't matter now.  The ironic part is the ingredient I am allergic to is the antihistamine!!  How can I be allergic to the ingredient that's supposed to be preventing allergies?  Rayne fail.  So now that there is absolutely no upside to getting sick, I better figure out a way to never catch anything again...lol.
