Sleepiness After Eating

Hello all, I am new to this board and I am so grateful I found you all. It's such a relief to realize I am not alone in this battle. I am 70 y/o and have been suffering from long-Covid for nearly two years. I did not get the "jab" and was very healthy and active before getting Covid in February 2024. Now, I struggle through each day. My symptoms are the typical extreme fatigue and shortness of breath after any moderate exertion. So far, nothing has helped, but I am still hopeful and still searching...as we all are. My question today is about the inability to stay awake after eating. No matter how large or small the meal, or what foods I eat, within 30 - 40 minutes after eating...I fall asleep. And it isn't a short 20 minutes or so....it's a solid, deep, 2 hour nap! I start feeling incredibly tired, my eyelids get very heavy and I just cannot stay awake. My body gets a heavy feeling, my arms and legs ache, I get a ringing in my head and I simply fall asleep. I've tried everything I could find online to fight off this effect, but nothing works. Has anyone else had this problem associated with Covid and what are you doing to fight it?
