Ok I just realized this is an old thread, but just in case you do read it again mellowman, I'll tell you what i think i told the last dude, cus he was askin about household highs also. If you get a can of whipped cream, wrap your lips around the nozzle while its pointing up, and press the valve or whatever its called, the gas that goes into your mouth is N2O, (nitrous oxide/laghing gas/hippy crack) the same stuff they give you at the dentist. You can inhale that and it has a funny dissociative anesthetic effect on you for a short while. Or you could just take a bottle of robotussin cough gels, whatever floats your boat.
