>Stimulants have a habit of being enjoyable at first ... and then the effects wane over the years

The standard approach to addressing this is thru the use of "drug holidays," regular short periods during which one doesn't take their medication with the intention of abating the growth of tolerance. I much prefer going this route since stimulants have proven to be such a solid solution. The other standard approach is, of course, upping dosage, which could be seen as only delaying the problem.

I don't disagree with anything you wrote, though. The internet is indeed a terrible place to get any advice on these topics.
