Do not fuck around with sleep deprivation. I developed severe insomnia to the point where at my worst I was averaging about 90 minutes of light sleep per day. After a few weeks of this I basically lost my mind. I could not function, I became paranoid, suicidal, violent, and a whole long list of scary bullshit. Worst of all, it all seemed perfectly normal to me. I was convinced I was in the right even though, in hindsight, I was batshit crazy.
