I am of the theory that Taking 'some' is still better than taking 'none' .....
I've been pondering that myself, even tho I am not on Tamoxifen (it is the only one I haven't tried!) . I only lasted 6 weeks on Letrozole, then 6 months on Exemestane & currently about 6 months on Arimidex so it looks like the honeymoon period is officially over! It now seems to be the '6 month mark' for me that the nasties start happening. :( Currently, I have massively sore feet 24/7 (I didn't have that on previous meds) and my left hand is starting to seize up again . grrrrr
I still have a couple of packs of exemestane - I wonder if swapping back to that could make a difference ....
