I was on letrozole for 3 years & came off it in October. Started exemestane last month. The 7 month gap makes me realise what letrozole was doing! Big improvements with hip joints, and my feet have been
lots better - I had awful stiffness & pain in feet; it really hurt getting out of bed in the morning.
Also the hot flushes disappeared!
Tip: get face & body cooling mist spray from Boots - helps when you feel like rushing outside and sticking your head in a bucket of water but can't!
