Sorry you’re feeling like crap, Chris. Everything I’ve read says the symptoms clear up within about 48 hours from the time you got the second injection. You get the full crapalalooza because you’re still a young buck. Us geezers don’t tend to get much of a reaction to the second dose. Your immune system sees the vaccine for the second time and issues a 911 call that makes you feel like shit. Our older immune systems are like, “Hmm, I think I saw this stuff before, but I really don’t remember that well. Oh well, the geezer is gonna die from something pretty soon anyway. No point in getting all worked up over it. Zzzz.”
