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.
