Conversely, I have been considered to be neurotypical all of my life, though I do have a lot of other issues (chronic illnesses) so I wouldn't rule out it being missed because of those ending up taking up all of the "bandwidth" so to speak - and I can think of very few daily habits that I have off the top of my head. Or, they're cloaked in a way that I don't "feel" they are habits, I'll try to explain that a bit better:
Most things that I do, it almost feels like there's an explicit direct cause -> effect correlation as to why. I suck at remembering to brush my teeth. But showering? I do so because I hate when there is that feeling of my legs running against each other in bed and there's an almost sticky (?) like feeling.
And I'm reminded of that feeling because unfortunately for me, laying in bed isn't only a thing I do during bedtime and occasional certain "activities with others" which is when they say is the only time of the day you should be in bed. I'll get the aforementioned feeling and go "I need to take a shower before I plan to actually sleep".
Or sleeping doesn't tend to be a habit that I have in terms of going to bed at a specific time of day/night, I do so because I feel the amount of energy I have is too low for me to do anything more productive in the day (or to regain the energy by having say a meal). Exception of course is if I have an early appointment the next day that I know is going to require me to need some amount of rest for, and even then actually falling asleep is a struggle.
Or speaking of meals, I don't stick with a explicit "three meals of day" plan - I usually skip breakfast and only have (maybe) lunch and dinner. I'll just have something to eat when I directly feel hunger and realize I haven't eaten in X amount of time. I'll have a couple of light snacks here and there to bridge the gap if I need to. This one though, I feel is more or less related to how my GI condition plays a part in my own internal risk vs reward scenario.
I also don't necessarily feel what others/my friends might describe as an almost instinctive desire to check social media whenever I wake up - I run the Lemmy instance I'm on so of course I do check to make sure it's still running, and this morning in particular I didn't have anything else that needed immediate doing, and came across this post in "All".
I use reminders on my phone to make sure I take my medications at an appropriate time since my sleep schedule is not consistent enough for me to just always take it when I wake up / before I go to sleep (I've been told that some of the ones I'm on work best if you take them at roighly a consistent time).
I work from home and clock in on time because I'm always looking at the time when I know it's around the corner, but I still have alarms and calendar events set to nudge me as well however.
I do my laundry when I go to take a shower and realize I have fewer choices of clean clothes to pick from, and set a reminder for the next day to do so. Similarly, I order more groceries when I have fewer choices of food to pick from (which thankfully doesn't involve running loud machines that will wake up others, so I can do that immediately rather than deferring it to the next day).
I charge my phone and my watch when I get a notification that they're low on batteries, not as part of a going-to-bed-ritual (and this certainly has bitten me on plenty of occasions).
I guess a better way to describe it all is that pretty much everything I do is "reactionary". I do everything as the need arises, nothing (well, off the top of my head) is really automatic in the same way I see from others. Most of the time I can tell you what prompted me to do something.
I will say that I have what I (along with my psychiatrist and therapist) can only describe as "rolling chronic depression", but even when it affects me the least, this doesn't change.
