Estimate of % of patients who achieve long remission?

Summary

Reached about 85% function after roughly 10 years, well enough to exercise and run around after her children, though still unable to build fitness and with poor temperature regulation and bouts of exhaustion even during that remission; no specific treatment is credited in this post. The remission ended after she took on many commitments and caught measles, leaving her "much sicker this second time...and for longer" than originally.

Symptoms mentioned

Symptoms: Temperature regulation.
