When I get that sick I make rest my full time job.
My family calls it “SpongeBob duty” and the fastest way out of feeling like hot ass is to hunker down as hard as you can. Make it a point to shut off your brain, load up on meds, and sleep as much as you can. Like others said, hot soup and nutrient dense foods are your friend. Brainless comfort TV to keep your eyes occupied while they’re open, and doomscrolling is to be avoided if possible. Play low effort games if you can’t tolerate tv or a movie.
The more aggressively you rest the faster your body can heal, and accepting that you can’t do shit except stay put for a day or two (easier said than done) will help. Godspeed, soldier 🫡
