Fatigue from eating?

Does anyone else feel extremely fatigued from eating? Like the action of chewing food? I always find myself out of breath from chewing any kind of solid food and I don’t know if it’s a me/cfs thing cause I’ve not heard of anyone experiencing this. I also don’t think it’s just from chewing, I think swallowing is exertion for me too because I will have a similar feeling when I eat semi-solid food like mash & gravy (my autistic safe-food) but it’s worse if I have to chew the food first like a sandwich or pizza. I can barely get through like 2 bites of a pizza without feeling exhausted (thankful for my partner who lets me just steal food from him so we aren’t wasting a whole meal that I won’t be able to eat). I have noticed that this started during a really bad flare up (stuck in bed, 0 muscle strength) that I am now slowly recovering from. I’m kinda just wanting to see if anyone else experiences the same thing and if anyone has any tips / advice.
