I totally understand why NT people would think - well, if having ADD makes you late, why don't you put some strategies in place like setting a couple of alarms?
The answer to that is (and this is not an exaggeration) if I put an alarm on for everything I need to remember but actually often forget on an average day I would have alarms going off all the time.
A good example - I take medication for another health issue.
I've taken this medication every day for 8 years. If I don't take it I have horrible withdrawal side effects.
I forget to take it all the time
It makes me feel really, really ill when I forget. I want to remember, I just can't.
I find it difficult to remember to brush my teeth, to have a shower, to take my medication, to decide whether to have breakfast, to feed my cats, to take my laptop to the office, to take the charger for my laptop to the office, to remember to take my card so I can pay for lunch, to take my security pass, to take my face mask, to remember the way to the office when I'm driving...
And this is when I haven't lost anything that I need (which is frequent).
I have some coping strategies in place for these things but imagine how many alarms I'd need between getting out of bed and leaving the house?
As a NT person - you just see the lateness and it seems so easy to fix. But it's one thing in a list of a million things that are difficult for me to do.
And I'm not always late. Sometimes I'm on time but sometimes...like at the moment when I'm also doing a 'big job' and under intense stress from financial problems from the pandemic it all goes a bit more to shit.
