Prolonged or re-occurring reaction to a Covid Booster while on Evenity

I had a Covid Booster on a Friday morning and by evening began my typical response to the booster, some chills and didn't sleep well. All day Saturday I felt awful, slept well Sat night and was fine on Sunday - all typical for me. On Monday I was very active, some cleanup yard work, an aerobic, 1 hr plus exercise class, and some other focused exercise. Monday evening I was chilled & didn't sleep well. The next 3 days I continued to feel chilled, very, very achy, fatigued and poor sleep. A very slight cough has developed. No fever, no runny nose... I feel slightly improved this morning. Anyone else have a similar experience??
