Hi Mediagirl, I recently stopped taking Tamoxifen due to side effects, only lasted 7 weeks.
Tiredness, constant nausea and indegestion, thrush in mouth and lady bits, so sore.
It felt like my body was a dead weight.
I knew I could not tolerate all this as already have health issues, pain from spine injury.
Its wierd how some get no side effects of note and others get lots.
In then end its our choice what we can manage.
Have you looked at the NHS PREDICT online tool, it shows how much drugs help improve life expectancy for BC or not.
I see oncologist in month or so to discuss other drugs but I don't think I will cope, I want to try, but have limits.
Its worth exploring what benefits you will get.
