After reading Dr. Courtney Craig’s blog, Lessons Learned from Tracking Sleep for 9 Months, I decided to give the app “Sleep Cycle” a try. I have found it to be one of the best $5 I’ve spent on this ME/CFS journey. Attached are some of Dr. Craig's graphs from Sleep Cycle. After two weeks of using Sleep Cycle, I’m getting some good data on which drug combination, bedtime, and activity level seem to give me the best sleep. Some of the data is contrary to what I had believed. Who knew? Anyone else using sleep tracking apps with success?
