This one speaks to me on multiple levels.
It's a reason I dropped my scepticism of medication and went to get a diagnosis and subsequent prescription. I am glad I did - and that it worked first try. (It's not guaranteed anything would, depending on unknown factors and probably autism also influences the effectiveness)
I can confirm: At first, it really feels that way. But now, half a year later, it balanced out a little and I am only medium fast. Still - much improvement compared to before.

I was the dog on concerta, also went badly after a while and I couldn't eat anything at all. Now after a lot of years I'm on Elvanse. While it's not as good as the concert, I am still able to eat.
For me it feels more like the dog went from a somewhat ruly Great Dane to a somewhat ruly cocker spaniel. A lot easier to handle on the walks and less attention aggressive but when it is it doesn't take all of my energy to get it home.
