My experiences with nitrious
I always used the whipped cream dispensers, instead of balloons. They're much easier to re-load in between huffs, and I tend to let go of the next balloon while inhaling. I always kept the cracker on hand for guests, though.
Me and my wife's ritual was to get a case of nitrious (12 boxes of 24 chargers) It was around 100 w/ free shipping, so good deal. Then we'd each do about 2 or 3 E pills.
We would each usually do about 3 or 4 chargers in a row (until we each got our own dispenser) with no breaths in between, just nitrious. Then we would give each other blood chokes, or "head rushes" as we called them. Where you press on the arteries on your neck and restrict the flow of blood to your brain. In the background, was usually some trippy music with winamp visualizations. And this would go on all night. Usually, we would have to redose on the E after about 6 ours though.
The combination of the E, nitrous, and "head rushes" was just great. Best combo of anything I've ever done (2nd place is dope + K). I love "head rushes" I must say if you've never done them, you're missing out. It's a free high that potentiates any drug.
I did find that after about 4 or 5 chargers I had to take a break cause my head would start to ache. Not my wife though. She could sit there for hours and never stop. One time when the case arrived, she sat there all day doing them. I asked her on my way home how much was left, and she said "some". So , I get home and there's 2 boxes left. She sat there and did 240 chargers all by herself that afternoon.
I got so spoiled that the first time I did heroin, I was expecting a feeling as good as that, and was SO let down. Not that I let that stop me from getting hooked, but that's a different story.
