Not a good med to overdose on. Your height/weight affects the effectivity of that sort of medicine. Some 17 year old girl attempted suicide with 270 mg and it didn't kill her, just gave her a higher heart rate lol. an 8 year old tried it with 210 mg, also didn't work. Pick a different poison, one that's not already heavily restricted for those of us who really need it... We don't need it taken away on the fear of us trying to kill ourselves if we relay to our doctor we're feeling suicidal. :/
