Anecdotally I have the same problem - I was really well managed with adderall IR but now I’m on vyvanse because of the shortage. I think the problem is it never fucking wears off - sounds good on paper but the cumulative effects of dehydration, not eating as well, and not sleeping as much really take a toll on you. Plus while it technically lasts longer, for a lot of that tail end it’s barely effective at managing ADHD (acute tolerance, depletion and tiredness) while still messing with sleeping/eating/hydrating.

I honestly think adderall IR should be legalized too if we’re going to legalize vyvanse - just put it behind the counter like Sudafed.

This stuff was legal, widely used, and widely available in many countries (Germany, the US) for multiple decades and it didn’t collapse their societies. If you read about it, generally the only times it caused problems was armies and such ran out - what people experience right now with all the shortages that wouldn’t exist if it were treated like Sudafed. Sounds like it’s scarily addictive given that, until you realize we’d also have a lot of problems if we ran out of coffee or caffeine.
