For menopausal reasons and especially at your age, I am glad to see your doctor gave you
estradiol and only that (no other estrogens in the mix). As far as the patch goes, use trial
and error if you have problems with it sticking. Also, sometimes if you are exercising frequently, you may be metabolizing the estradiol rather quickly, so keep a list of symptoms as they occur so that you can share this info with your doctor in case a dosing change has to be made.
