From Tamoxifen to Arimidex

Hi Jane, I too have been on tamoxifen for about 2.5 years and it has been suggested to me that I switch to an AI. I have been reluctant to make the switch though because I haven't had any major problems on tamoxifen - mild hot flushes, hair not as thick as it used to be is about it. Also I've read a lot of posts here and elsewhere from women on AIs complaining about aching bones and joints and feeling like they are 20 years older. And libido?  You can forget about it apparently. I realise there is a slightly greater decrease in recurrence risk with an AI and that tamoxifen has it's risks too but when I weigh it all up tamoxifen looks better to me. I know I have to accept being getting older but the idea of blocking all estrogen production in the body seems very depressing to me. Yes I'll be 50 soon but I don't want to feel 80. However, I haven't actually tried it so maybe it's not as bad as I fear. Would be very interested to hear from you if you do make the switch.
