Yeahhhh. My overnight RHR and HRV go absolutely wacky even with a single drink the night before. That's not to say I don't still have a drink sometimes, but watching my vitals has really made me aware of exactly how much impact it has. If I have 3-4 drinks in a night on a special occasion it will take days before my HRV and RHR return to normal, even if I don't feel any physical effects at all. Still fun, but I'm definitely aware it's not good for me 😂

It is just the alcohol telling you heart to chill, no biggie.
