Can’t say anything about the legal consequences; typically, an ADHD diagnosis does not affect any rights and is confidential anyway.
Keeping your health situation very private is a good idea for any health issue.
As for not needing them: Per definition, you don’t have ADHD if it does not significantly impact your life negatively. It’s a “must”-criterion, no matter how many other indications there are.
But if you benefit from it, my experience is that it only changes the things about me I disliked. Everything is only better. Only thing to watch out for is not to use the medication boost to focus even more on unproductive things.






Thanks for pointing out the potential (?) link to protein! After 1.5 years on it, I fell into the mistake to binge-eat junk food in the evening, which will probably make anyone feel less fit, but I wrongly attributed the following fatigue it to the dose and duration. Others report problems with caffeine.
