I tried to get the courage to ctb 5 years ago with nitrogen method. It took so much planning and then I couldn't go through with it, freaking SI. Biology can be a bish sometimes.
I've also overdosed heavily on sleeping pills but partly knew I would wake up.
Recently (a month ago) before finding SS I was ignorantly thinking I can use sleeping pills, alcohol and a plastic bag. One attempt I fell asleep before pulling the bag over my head and the 2nd attempt i pulled it over, sleeping pills knocked me out but must have ripped it off from the CO2 effect later. I woke up a bag with a lot of condensation in it. I must have been close.
Nobody knew about these attempts. I just have to go to work and carry on with life. Which is nice but also pretty traumatizing.
So next time more equipped with SS tools. Now to overcome SI! :/
