Honestly, no, not really... I have done all 3 ( on seperate occasions) and that doesnt seem like the best combo... Something about ambien and nitrous doesnt sound pleasent to me... I would personally do the k pins and then ambien after to sleep great and for the nitrous do half of what you plan on, get nice and high and so the rest...
i personally would ditch the kpin and save it for later when you're going to bed. ambien and nitrous might be kind of interesting but there are definitely better drugs to do nitrous with, weed and psychedelics are the best for that.
Ambien and nitrous sounds like it has potential but i think adding a benzo into the mix is going to knock you right on your ass. Benzos and nitrous sounds like it could be fun too. Maybe you should try all 3 and let us know
I don't know about kpins...but it seemed like the times i've mixed xanax and ambien, I didn't get the more trippy effects that I usually get from the ambien.
