Stopped drinking one week today. Just wondering if it

Stopped drinking one week today. Just wondering why this morning I felt like I got a hangover? Not a big hangover, but just feeling like I drank the night before even though it's been a week....is this common to feel like this??

Congrats to your first week sober! Maybe…I read it can take up to 10 days for the alcohol to clear your system. Or maybe you’re fighting off a cold, who knows? :face_with_monocle:

I was thinking the Cron. I had it and it felt like a bad hangover.

I think it's just a sinus cold. But it felt like a hangover, and made me wonder....
