THat sucks its like a 200 pound person taking 200 mg. Definately not good for him. I would do what I can to make him throw it up as much as possible and I really hope he is o.k. And after this ordeal is over I hope you learned a lesson about how assinine it is to leave things like this in the open. I hope you dont have kids running around. We all make mistakes so I am not totally talking smack but hopefully you think about that stuff a little more from now on. I am glad they were only 5 mg/ea
