Hi @tulip56
A multitude of reasons. See my thread
I had n 8 week break in the end, was 4 weeks then waited for prescription to come in the post, first one got lost so another few weeks wait, hence 8 weeks. I found the hot flushes, fatigue, poor sleep and aches and pains reduced after a few weeks. It took a while for the Exemestane symptoms to start. I watched a BCN Live with an oncologist ( see their YouTube channel, I think it was a female doctor) and they said as the drugs builds up in your system so side effects can become worse and breaks can help you continue the treatment long term. So always worth asking for a break first and see how it affects you.
