Method #1 and #3 would be the best choices, but still not a sure bet. Method #2 you would pass out and throw up most of the drugs, and probably survive with permanent damage to kidneys and liver. Method #4 would require a lot of willpower, and when if you do pass out your body's spasms will most likely roll you over and out of the water.
Just buy a small tank of helium, put a thick plastic trashbag over your head, duct tape around your neck with a hose running from the tank on VERY VERY low.
