Death by Drowning

I pondered whether it would be possible to kill myself by inhaling a glass of water. I'd have to inhale as hard as I could while I had a mouth full, and hope that my lungs couldn't expunge that much water before the lack of oxygen shut down my brain. What led me to this line of thought was the lack of alternatives: I was bound to a chair in a small grey room, my only interaction the meal of bread and water I received once daily. The cyanide pill that my colleagues and I agreed to keep had been taken from me with the rest of my belongings when I was knocked unconscious and bound to this chair. I resolved to try it at my next meal.
