Why do I still feel awful after the Covid booster?

Let me preface by saying that I am 100% pro-vaccine/anti-communicable disease. I was one of the first in Florida to get the Covid vaccine when it became available, and get my booster every year since. I understood and expected to feel awful after getting the initial doses, but still after every booster I feel the same. Exactly 12hrs after getting it, I come down with intense fever, body aches, chills, I feel like I got hit by a bus. Last year my fever shot up to 103.5° and it took 2 Advil, Tylenol and a cool shower to bring it back down. And then it knocks me out for like 1-2 days afterwards with fatigue, but then I’m totally fine and go on with life. But I feel like I have to plan for it, because I know I’m going to feel so awful. I’ve heard that the new Novavax (Nuvoxid?) vaccine has less side effects. Has anyone gotten it? And does anyone else also feel just as awful after getting their booster?
