Was having a talk with a good buddy, asked him (while we were both hungover of course) if he ever has deep feelings of regret, worry, anxiety, when hungover. We didn't even do anything wrong, pretty chill night, but for some reason I felt bad about it, like I was a bad person having indulged myself. He tells me it's a normal reaction when hungover. So that made me feel better. Don't know why it took me so long to know that. Anyway I hope this little tid bit helps the posters of this thread realize that "You are not a bad person just because you got super mumped up last night. There's a scientific reason you feel this way. So get over it, you're fine."
