Hi @NatF it sounds like you are on the home run, and not long to go before you can put the AIs behind you. Each person has a different type of experience on the AIs, and for me I lasted on them for four years, probably due to severe pain in my knees while trying to sleep and waking at least 30 times throughout the night (I kid you not). I also had very bad memory and was very forgetful whilst on the AI, and also taking a thyroid medication which can present with similar side effects. I just didn't know if I was "Arthur or Martha" most of the time. My oncologist was happy enough I discontinued on the AIs, as in my case my Ki % was low, and the most benefit for me was in the first 3 years of taking the tablet.
Maybe you can see if there is another AI that may get you over the finish line, it could be worth a try. I was also postmenopausal when diagnosed, so there are many factors to take into account and also what other health conditions an individual is already experiencing.
Take care and I wish you all the best with your decision. xx
