Method suicide by balloon suffocation is possible?

[meatlobe]

Hi, i need an easy way to ctb and an idea of mine was to try and see if it's possible to suffocate myself with the balloon similar to the helium tank ctb method. Unfortunately I'm unable to use the helium tank method because of the cost and because family is around often.

This will not work at all. You exhale CO2 into the ballon and re-inhaling it after several times will make your body freak out coz the CO2 alarm is being activated.
