DRAGON ENERGY DRINK

I bought dragon yesterday and immediately after taking the drink i started having stomach pains which lasted all night up until now. Not sure what could be the reason but i think there could b e a flaw in your production line. Had one on saturday but nothing happened. Yesterday's one tasted even different, please check. WIll see a doctor and hoping its not a bad damage. I begin to wonder now why the drink is banned in other countires. Anyone with similar issue?
