Please add higher cholesterol with Arimidex and hair thinning and brain fog/memory, or did the brain fog ramp up when I was on Letrozole for 6 months ........... see? I can't even remember now. I also get ringing in my ears, but I think that is left over from chemo. Oh the joys that go with all the trials and tribulations of being on the cancer bus! All this crap threw me into early retirement and I am still not at retiring age yet, yep keeping positive should be my motto, not my name here. Excuse the rant.
