Hi Corinna
I hear you about the foggy brain and low energy levels. I am just starting to look at and apply for jobs and I worry about how I will manage the afternoons. Thats when I get really tired. I also have lots of strange aches and pains. Sometimes I feel really jittery, then it goes away. I completely understand your change of attitude towards living in the here and now. That is my greatest challenge and what I try and achieve. I read somewhere that we should live like cancer wont come back otherwise cancer is the victor. So that's what I will try and do.
Good luck for 2016 and keep up the exercise, it can only be good!
Lisa
