letrozole

Hi been on letrozole for 6 yrs(being on a trial) have recently noticed an increase in anxiety and stress. had a tia 3 yrs ago but was told letrozole was not responsible. not had blood tests to say otherwise but letrozole does carry these side effects. is there anything i can take or do with letrozole. on it for a further 4 yrs due to trial. never had these stress levels before with an increse in blood pressure. am on high blood pressure, statins and blood thinners due to the tia. dont want to stop taking the letrozole just in case.

Thanks

Tracey
