I was supposed to do boring life stuff today but I got heavily sidetracked by trying to model a physics problem.
This sort of distraction happens a lot to me, when I'm meant to be doing one chore but drop it and do a different one when I see it needs to be done. Like needing to clean the stove, then noticing the cupboards aren't clean, and then staying up late cleaning my kitchen from top to bottom. The sort of thing where it's hard to find motivation but once I do then I'm unstoppable.
I have a friend on adderall, and how he describes that drug it wouldn't work to help this because it helps you focus, but not necessarily on the right thing. He once took it to finish an assignment and then got fixated on a videogame instead and played it until 5am.
I've had different experiences with different adhd meds. With vyvanse I had to be super careful because whatever task I was pointed at when that shit kicked in, that was the next 18 hours of my life. Schoolwork, video games, trawling wikipedia, whatever it was would fully consume the rest of the day. With ritalin and similar I can still get sucked into doing something, but if something shakes me out of it it's much easier to decide how to react, whether to ignore the distraction or take the chance to switch to doing something else. Now that I think about it I should probably have a recurring timer or something to make that happen more often.
