how much of an energy drink containing 32 mg per 100 ml of caffeine could kill me ?

I don't know what kind of energy drink you are drinking, but it would take an enormous amount of caffeine to kill you! You can drink ten cans, the worst that can really happen is you get shakey and jittery, but it sure won't kill you.

The amount of caffeine and sugar in an vigor drink is a lot greater than a soda or latte. Medical professionals advocate warding off all caffeine for the duration of being pregnant, but in case you have got to have it, to limit your consumption to 1 caffeinated drink per day. Alas for you, the caffeinated drink you crave is not comparable to a average drink with caffeine. You would frequently get away with taking a small sip of 1 day-to-day, but with gestational diabetes being on the list of concerns closer to the 3rd trimester, i would just preclude power drinks all together. I am also 26 weeks alongside (due 12/10) and i have been struggling to prevent Coca Cola...I could drink it like water! I know the angst of wanting to fulifill a craving...I'm hoping you to crave whatever else soon! Good good fortune! :)

The dose expected to result in death in half the humans that take it is 192mg/kg for humans, so as a "12 stone" person it would take (77Kg x 192 mg) =14,784 mg to give you a 50% chance of killing you, or about fifteen litres/30ish pints of "energy drink" in one sitting...

You will probably die of the physical injury resulting from your bladder exploding first!

how's your heart?
