No god please don't take Coricidin Cold & Cough, it contains antoerh active ingrediant besides dxm, called cpm. At high doses cpm is LETHAL. Don't even fuck with that, it could shut down organs in your body and shit.

Cough Syrups like Robitussin Maximum Strength or any other generic brand marketed as "cough" only, are usually your best bets. When you're browsing, check the label on the box to make sure that the only active ingrediant is "Dextromethorphan" or "Dextromethorphan HBr". Any other active ingrediants may kill you at the doses you'd need for the DXM to work.

Pleasae don't take CCCs, only prducts with DXM as an active ingrediant ONLY.
