So almost at the 50yrd line as far as the new treatment goes, side effects are getting a little cumulative, and for me, the worst is the lethargic feeling I get from onco meds. Brutal at times, especially when you are doing something you've done a 1000 times, such as walking up a flight of stairs that I was able to do with ease just a short while ago, but now feels like a marathon. Go for a walk, or better yet a run if you can would be the best advice I could give anyone.
