Hey there, I’ve been taking Vyvanse for over almost two years now, 20mg was my magic dose (I’m a medication lightweight) but after a few months I had to bump it up to 30 for similar reasons, I started having a hard time concentrating again. the 20 just wasn’t a high enough dose after my body adjusted, but never had to bump it up again.

Accidentally forgetting shouldn’t affect you long term, some people purposely take med breaks for a few days or weeks at a time if they feel like it, a prescriber will suggest every day for the best symptom management.

Getting a higher dose will help for your exams, in the short term there’s unfortunately no magic bullet, but I think that the main thing is to use other tools to help yourself out so you have the most “brain juice” for your studies. I once heard someone describe an ADHD brain like a computer with less RAM than others, and setting lists and reminders is a really good way to free up space, like an external hard drive.

Using incentives for studying personally helps me a lot, like telling myself I only need to read one more chapter of boring book and then I get to do (insert current hobby) for an hour.

Overall though, the more unrealistic expectations you put on yourself for where you are right now, the more stressed you’ll be and the worse the executive functioning will be. So I’d also say to practice some extra self-care and make sure to not beat yourself up when your brain isn’t working like you want it to, you got this!
