Hi Di,
I'm not quite to my 2 year anniversary, but like you I also had sleep problems. I'm on Arimidex and was told to take them at night so that if you get any side effects you'll sleep through them......yeah right!!! All they did was make me NOT SLEEP. So in an event to get a decent nights sleep I switched to taking them first thing in the morning and I cannot believe the difference. Within a week of the change I started to sleep really well albeit I get up to go to the loo a few times and often have a drink, but then I go straight back to sleep till the alarm wakes me at 5.00am to take my dogs out for their and my morning walk.
I too have the aching knees and am taking Krill Oil with Glucosomine which kind of helps, but still feel like a 100 year old woman. Guess its a case of keeping on keeping on.
xoxo
