Boom and bust
A few weeks ago I had a good couple of weeks. I felt energised and maybe did too much physical activities. Then I woke up one morning a few days ago in agony. My knees were so painfull. I felt totally wiped out. I spent 2 days just sat on the sofa with my feet up dozing off every now and then. Iv heard this called /he boom and bust effect. Anybody else experienced this?
