I started taking Tamoxifen in December and started radiotherapy in January.
in first few weeks I noticed a few side effects but did my best to ignore them. Generally now I notice a lot less (or I‘ve gotten better at managing them).
I felt very fatigued towards the end of the radiotherapy. I used an app called Untire. I found this really helpful to understand why suddenly I was totally drained and also to manage my energy levels better. It was frustrating but that app helped me to manage myself.
Wishing you all the best
