What's so great about Nyquil?

I was getting sick with lots of trapped phlegm and scratchy throat, and so Barn and I made a late night trip to Price Chopper for some Nyquil and ice cream. I took what one might consider to be 2.5 adult doses and [eventually] went to sleep. I feel like a million bucks this morning, I mean it! One million dollars! So what's so great about nyquil? I've looked it up:

Dextromethorphan (DXM):

DXM acts centrally to elevate the threshold for coughing. At the doses recommended for treating coughs (1/6 to 1/3 ounce of medication, containing 15 mg to 30 mg dextromethorphan), the drug is safe and effective. At much higher doses (4 or more ounces), dextromethorphan produces disassociative effects similar to those of PCP and ketamine.

STREET TERMS: Orange Crush, Triple C's, C-C-C, Red Devils, Skittles, DXM, Dex, Vitamin D, Robo, Robo-trippin', Robo-dosing.

DXM EFFECTS: Euphoria, enhanced awareness, impaired judgment, loss of coordination, dizziness, nausea, seizures, panic attacks, psychosis, brain damage, and addiction. Coma and death may result from taking cold medicines with DXM.

Oh.

That's funny, on the bottle they say that it's for "cough." Next time, I'm getting the generic stuff. That means I'll get my Vitamin D for much cheaper.

Time to iron my physics book in hopes of selling it back today! Won't be able to look up stuff about PHYSICS anymore, no siree.
