Does anyone have any info. on aerobic capability loss with chronic fatigue/FMS? This was a real problem for me, which got progressively worse. I found that when I treated my sleep disorder, as well as started taking meds (SNRI), The aerobic capability improved in a major way. I never stopped exercising with the FMS, but the pain and fatigue limited the way I did my usual regimen. I was afraid to bike ride, or climb, because of the fatigue. I can bike now. Anyone have any links to research, doctors who have discussed this, experience with this?? Thanks.
