Help how to force yourself to stay awake

[shadows_and_silence]

every single time I'm about to ctb, i end up getting so tired and just lay down to go to sleep. it would be really nice to be able to attempt my method (ligature strangulation) multiple times so i can eventually find my sweet spot and succeed, but i always get comfortable in my bed and fall asleep. does anyone have any advice?

I was able to try to partial hang again and again throughout a whole night one day cus this ctb attempt was caused by intense emotional pain and being triggered by memories which made me have the energy to stay the whole night to try to kill myself. Maybe try doing it when an big emotional urge to die happens?
