Hello. So sorry you’re feeling like this. I’ve been in letrozole for nearly 3 years now. I don’t know if it’s because I’m used to the side effects or that they have eased off but they’re not a bad and are more manageable. Like someone else said, you’re covered by the disability act now so it’s definitely worth talking to work and working something out. Be honest and tell them what you need to be able to work. I saw occupational health and they were brilliant. They suggest work put in place things that I hadn’t even thought about. Hope you get back to work soon
