text: metabolism/? my girlfriend just got ferinhiet, i think is what it is called, anyway... its a pill to boost your metabolism or something... i was wondering if it'll harm her, or even if maybe it'll screw up her metabolism? it will do more harm than good. it is no more powerful than caffeine. it causes headaches. it also helps people develop bad habits. frankly, she should get involved in a diet program through her physician and join a gym.
