Tried nitrous for the first time yesterday. I put 1 8g cartridge in a cracker. Some leaked when I tried taking the baloon off but I inhaled it anyway. I waited for a few seconds, felt a numbing sensation quickly going thru my body from feet to arms, giggled once, and besides it being really easy to make me giggle for 2 or so minutes after, I didnt feel anything else. (not even sure if that's the nitrous, I think it was just the adrenaline)

I retried again today, took 2 cartridges without it leaking. After inhaling I lied down, I started giggling a little and started to see some white noise. I lied for about 20 seconds and it was over again.

I know nitrous isn't supposed to last but I didnt expect it to be less than half a minute

If I am supposed to keep inhaling it, then is that even possible with a cracker? It takes me longer to inflate the balloon than the effects last, and besides that's just a big hassle.
