It didn't work for me. I drank 10 bottles and within 2 hours it made me pass out hard and then when I woke up 12 hours later I was unable to stand without falling over for about 24 hours then everything went back to normal. My heart rate was pretty slow at one point but not enough to die. I really thought this would work. I don't know how people kill someone with only a bottle or 2, they must have some underlying disease. I might use it to help with another method like hanging or drowning because it did make it hard to stay awake and hard to stand up so maybe that will help.
