HI Deb, thanks for joining the site! We are glad to have you. There are lots of people here that have taken the Arimidex. You will get lots of input on this if you will repost it as a question in the question tab at the top of any page.
This site works a little different than some in that your status posts are only seen by the people who are following you. Give it a try and post it in the questions tab and lots of people will help.
Thanks for being here and let me know if I can help you with anything around the site.
