Why the hell are you smoking/taking Acetaminophen? That will not make you feel any highness. It is a mild analgesic with no stimulating or CNS affects. Don't waste your liver on tylenol save it for the good stuff....

By the way Ritalin is just the name brand for Methylphenidate which stimulates CNS activity similar to Adderall (amphetamine/dextroamphetamine...etc). Concerta is just a new extended release tablet form of Methylphenidate. 36 mg is a pretty strong dose second only to the 54 mg versions. The highness and pleasent feelings your experiencing are comming from the mix of alcohol and Concerta. The DXM would have made you feel good but not at that low of a strength. Usually no effects are felt under 120 mg. Pseudoephedrine might have a stimulating affect.

I think you will be fine... Just don't take that much Concerta its not good for your heart...
