Combinations - LSD + Nitrous = euphoric?... What else?

[crystalx]

So SWIM's best friend who is an exprienced tripper said next time SWIM solo trips, he should take a hit of NOS and it will be amazing. Is this true? Anyone confirm this? If SWIM doesn't have access to NOS, will whippits (hits of right-side-up whipped cream canisters) do the same thing?

Does anyone else have any ideas of LSD combinations that last only a short period of time? K seems to do this, but again K is very hard for SWIM to find; whippits are readily available at any local store.

Thanks.

If no one knows, SWIM will update everyone when he tries it on Friday
