Do you seem to get angrier at night?

Not at all. Early morning just after waking up is when I'm grumpiest by far.

Coming down off caffeine, longing for a beer, adhd meds wearing off, hangry from a day of labor, bottling work drama to spare your significant other, house is a mess meaning you gotta keep working when you get home, no good food in the fridge. I dunno, seems like everything kinda hits the fan at night. Weekend nights, not so much.

When I'm tired, yeah. Anger is a "cheap" way of paying attention to something, and our brains default to it when attention is otherwise difficult.

Probably not relevant, but for awhile, I was taking Adderall and I realized it would send me doooooown in the evenings when it was wearing off. Vyvanse fixed that, in that instance.

Broadly speaking, I think it's somewhat normal to get a little down at night, maybe? You're tired/weary, you've worked all day, seems somewhat normal, within reason. But it could also be attributable to a lot of things besides just "the night," e.g. poor sleep, not eating enough during the day, extreme horniness, etc...

In the grand scheme of things I don't do 'angry' that much at all, but the two times when I am most likely to angry at all are commuting to work and then back again. Commuting to, because I will be fuming over the latest environment-destroying, genocidal nazi shit that has hit the news overnight and on the way back because I will be grumbling over whatever nonsense and stupidity has arrived on my desk during that day.

In both cases, I make a positive attempt to get it out of my system by the time I arrive at the end of the travel. I recall a study that concluded that a 16mins commute was optimal for that - which mine was exactly at the time.

I get more anxious

No, that belongs to the morning part of the day. Night belongs to sadness.

Yes, but not because of the night per se. But because I need silence in the night and I almost never get that. Daylight noise level is bearable.

After giving my daddy 8 hours of hard labour, yes

My mood does trend downwards over the course of a day. It's tiredness, I think.

The only times I ever get angry is when someone I like is getting slighted. Other than that I'm very calm all the time

I'm more of a last couple hours of work grumpy.

Nope as I am at home and I see no one. Well, except bf and my kitties.

Na.

No, I usually get tired during the night. I tend to laugh more easily if I stay up late.

Yeah, easier to get both angry and desolate in the evenings/nights. Also far more likely to give in to temptations, like trash food, candy, alcohol...

After a long day of being in control of oneself and making good choices, that ability gets worn out. It's worse if I've had to face a lot of stress or (mentally) say no to a lot of temptations or make a lot of decisions. At the end of the day I have no more "no"s to give myself.

It also gets markedly worse if I haven't slept, eaten, drank, been outside or taken sufficient breaks that day.

There's also the hormonal aspect, where hormones fluctuate on a daily cycle, which I think might be the reason I crash and want a nap in the afternoon, and get hungry around 23 regardless of if I just ate or not, and is the most focused and calm before noon.

I'm usually grumpy in the morning and feeling rarher down until 15-16, after that my mood gets a lot better, evenings and night time is best for me. If I have to wake up really early I feel just empty.

Elvanse can make the afternoon crash worse and it also causes a depression hour at around 17, I've tried taking half the dose in the morning and half mid-day and it seems to help with the crashes but it also makes the quality of my sleep worse...
