I've been taking Arimidex since Jan of 2000. There are side effects, joint pain being the most noticeable for me. I can't say that it caused me to be tired because I have other factors to consider.
I do know that it has caused me to have a beard and moustache and have very little hair left on my head. For me, this is something I don't like but something I have resigned to.
I hope things will improve for you. You can search the net for all of the side effects and see if that's what is causing it for you.
Good Luck, Jo-Ann
