@Teabaglady - I started on Letrozole & had bad side effects, then Exemestane that went the same way after 6 months - so changed to Anastrozole & have done MUCH better on it for the last 4 1/2 years! I've just passed the 5 year mark on AIs and I have the choice to stop altogether, or I can have regular breaks & continue for the next 2 years and then it will stop. So right now, I'm having a break from Anastrozole for 6 weeks ..... and will see how I go!
The AIs can actually make you more 'emotional' as well .... so the break should do me good. Take care xx
