@lisman1408 So far, sort of so good! I take mine in the evening so if there's any dizziness, it won't be bad. And it hasn't. Have a little achiness, but not like on the other two. I am only about 2 weeks out on this pill. I wound up with a torn meniscus from a fall a couple of months ago so PT has given me exercises for that and whether that helps me not have quite so many aches, I don't know. I also started up my after-breast-cancer PT strength training and have increased my walking. I start a water aerobics class soon and am hopeful that also invigorates my body...time will tell. I hope you do well with the Aromasin. Because of my family history of blood clots, Tamoxifen would be a bit iffy for me. Let me know how you do! I'm in northern California.
