For those who have never tried one of the two:
Mushrooms=good psychedelic experience. Shadows and shapes move and change, odds thoughts, fun time.
Nitrous=the good version of standing up too fast and getting all dizy and black out like.

I highly recommend this combination to everyone. If you like doing mushrooms especially it is great. The nitrous becomes a full experience which feels like it lasts 10-20 minutes. Basically, me and my friends call it the gateway to heavan. Everything becomes radiant, the trip becomes intesner, sounds change immensly. I don't know how else to describe it but as heavan, it is perfect.
