heyy Im a lucky canadia who get acces to OTC codeine. tho there a lot of caffeine in those, any danger in taking 300 mg of caffeine or higher?
I wouldn't take anymore than one at a time, at most it will make you jittery, assuming you don't have any other health issues. I've taken 400mg at once and that's about as much as I've got from it. But anymore may lead to excessive heart rate, sleeplessness and nervousness.
