Exemestane
"This drug is perhaps saving my life,  but who knows - and at what cost? Right now I seriously question the value of treatment that has such violent side effects. I'm experiencing: bone pain, extreme hot flushes /cold shivers, chronic constipation, vaginal dryness and discomfort, cognitive impairment, inability to concentrate, insomnia, significant weight gain (18bs in 8 weeks), rapid aging, facial hair growth, irritability, depression (big surprise there). It really angers me to see the glib way doctors document their research on this drug, claiming it is 'well tolerated'. I'm sure there are exceptions but in my personal experience so far, every woman I have met who's taking it complains of similar symptoms."
