How to sober up from robotripping/pot?

I smoked some dank ganja (marijuana) like 3 days ago and got pretty stoned, felt it the next day too, then the day after (2 days ago) I stole some tussin from acme and went robotripping, and everytime I wake up i feel buzzed (not quite high, but definitely not sober). So anyways, how would i go about sobering up? i know about drinking fluids and exercise, but what about other methods?
