Over the last 10 years or so my relapses have got more frequent. And recently, they also seem to be becoming more regular. No matter what I do, I have a relapse about every 4- 6 weeks (from end of one to the beginning of another). It does make life a bit more predictable! Does anyone else find this? I also have a friend with ME who has been relapsing every 2-3 months for many years. What's going on here?
