How toxic is your favorite pop/soda???

I only drink water....and squeeze a lemon slice in it if it's available. One big bad assed kidney stone was more than enough for me! Be careful with the energy drinks. I had a friend who was 33 years old....solid as a rock and in great shape, drank too many of those things one day and fell over dead as a door nail of a massive heart attack. :( R.I.P Joey
