I was diagnosed with ADHD and started on medication at 12, but not really told anything about what it meant for me or how to deal with it, and when I was 18 -literally when my parents dropped me off at college- was told I was autistic

Yeah, though tbh I don't know if I'm underselling them or overselling them. On the one hand the side effects can really suck when they happen. Reading back through my comment made me realize just how bad some of them are lol, and especially how bad they sound to someone who hasn't had 3 years to get used to them. But on the other hand they can be managed or avoided with relatively small changes to my behavior (ex: staying at school a bit later, having some food and studying while the meds wear off, and then finally commuting home once I can no longer focus on studying will avoid the depressed/tired state, and also helps me academically), and even when I do get the side effects I listed, they've never been so bad that I considered stopping with the meds, so for me at least the trade off is more than acceptable.
