There are honestly a million reasons why one person might bounce back from anesthesia feeling totally fine while someone else feels like they’ve been hit by a truck for two days straight.
It all comes down to the specific cocktail of anesthetics and painkillers used—including the dosage—combined with how fast your own body processes everything to finally "turn the lights back on."
But if I had to give you a really, really simplified version... the speed at which you wake up and shake off that post-op grogginess mostly depends on whether they used muscle relaxants during the procedure.
These are drugs routinely used in most general anesthesias—especially for those bigger, longer surgeries—that basically freeze your entire skeletal muscle system once they hit your bloodstream. We're talking every single muscle from the top of your head down to your pinky toe. Again, because everyone's metabolism is different, some people clear it out faster than others, which is exactly what rapidranger79 was describing after her thyroid surgery.
Now, about those compression stockings—they are literal lifesavers! See, even when we're wide awake or just tossing and turning in bed at night, our legs maintain a certain level of muscle tone. Whether we're walking, wiggling our toes, or just shifting around under the covers, that muscle activity helps pump blood from our lower extremities back up toward the right side of the heart. Unlike arteries, veins don't have their own muscular layer to do this heavy lifting on their own.
So here's the thing... when someone goes under for surgery, they get the anesthetic injected into their circulation along with a muscle relaxant that essentially "freezes" everything. That vital muscle tone just vanishes. Suddenly, the circulation in the legs loses its main engine, everything slows down, and the veins in the legs dilate significantly because the pooled blood is struggling to make its way back to the heart. If a few things go wrong at once, you end up with a potentially fatal blood clot stuck to the vein wall. After the surgery—sometimes quickly, sometimes even after you've made it home—that clot can just break loose, hitch a ride in the bloodstream, travel up to the heart, shoot into the pulmonary artery, and... bam... causes a pulmonary embolism, which can be instant death if it's big enough.
By wearing compression wraps or, more commonly nowadays, compression stockings before surgery, you're basically providing that "muscle squeeze" for your legs and preventing that whole nightmare scenario.
On top of that, doctors usually prescribe subcutaneous injections of Claritin, Clexane, or similar low-molecular-weight heparins to drive that risk of all this crap even lower.
