Hi dmcook, starting tamoxifen is pretty daunting when you hear about all the potential side effects, so here's to 6 weeks on it, well done you. I've been on it about 5 months now. I'm 47 and not menopausal yet. The first couple of months I sweated lots at night and didn't sleep well, but it just hit me the other day that all completely stopped somewhere along the way.
I've noticed I'm generally more achy, especially my feet first thing, I hobble for the first minute or so I when I get up, but it settles pretty quickly and until I thought about your post I hadn't really registered it.
Getting back into exercise (I do group personal training which has been great, the social aspect and the support as much as the exercise) has made a huge difference, I'm much less achy and sore, and it helps me like my body again, instead of seeing it as something to let me down, if that makes sense!
I thought it might help knowing the side effects often do get less or even go with a bit more time. All the best xo
