This group is quite helpful and helps me to connect the dots. I never thought of the medications as being to blame for the fact that I can no longer do my chin-up routine. I tended to blame my age (82) and a shoulder injury which caused me to lay off. However, my brother went through a 2 year course for his prostate cancer and he complained about a loss of energy so it starts to make sense. Thanks to Mayo for hosting this group, which I look at as a support group.
