Well ditto to everything you have said Ann Marie. All of your symptoms have been the same as mine.
I joined an breast cancer meditation group that meet every monday at our local community centre. I felt like I had so much more energy right after the meditation.
I have been too lazy and sore muscles to go back to pilates I found it too draining on my energy. So not so sure how I would cope with yoga, maybe once treatment is finished.
I have many types of meditation on my ipod and found it very helpful. Also just listening to music - I have found this very uplifting.
There are lots of guided meditations on youtube.
I am suppose to start on the taxotere in 2 weeks, but have an ultrasound tomorrow which may change my plan - wait and see!
All the best
