    Hi @Pommy8
    Different people get different side effects and side effects can take differing amounts of time to kick in. So it may be the Letrozole but it may not. Are there any changes in your normal routine that may cause a change or are you taking any other medication or even herbal additives that might react with the Letrozole? If not, may be worth discussing with your oncologist or GP. Best wishes.

    @Pommy8. @Edithead - that's a bummer ... as @Afrasersuggests  -  definitely raise the issue with your GP and Onc - and ask for a full body check up - full bloods, heart & liver function, diabetes, electrolyte levels (salts & minerals in the blood - fatigue is common if levels are low) ....get everything checked ...   

    Maybe even request an ECG & a stress test - so you have a 'picture' of how things are now, to compare with others further down the line.  Were either of you on chemo? If yes, Which one?  Sadly, some are known to cause heart issues further down the track  :( 

    Keep a list of how it is affecting you to take to your appointments & take care xx
