Query: DANGER!!!!!!!!!!!!!!! DEADLY

I took 2 viles of this stuff & 10 hours later was in the ER feeling like I was about to pass out & never wake up. In all fairness I did mix it w/ alcohol, but the dosage of just one vile (which the box recommends as a daily dosage) is 5,500mg.'s. Most books & websites recommend no more than 500mg.'s a day! Who knows what is actually in this product. I've thrown away the rest, as I never want to feel that out of it & scared of falling asleep. I felt weak & light-headed for a week after.
