never taken it myself. two different friends i know have. one was sick as a dog, but she was usually poorly anyway lol. the other had a bit of cramping, but nothing else. i think with most medications it depends on how your body normally handles meds. my mum, for example, gets every side effect under the sun, where as my dad and i never have issues at all.
not even sure how to go about getting here. should probably ask one of my friends for piece of mind.
