Hi Jill
In an odd kind of way you are one of the 'lucky' ones. Seeing as you've had a hyster, you won't have to go down the path of using progesterone, which for a lot of ladies is the tricky part of HRT.
You might need a do a few tweaks to your routine before things settle, but generally speaking women do well with the patches, and the good news is that there is now no longer any justification for doctors not prescribing estrogen long term.
