Medication is not the only way out. Changing drug regimes or doctors isn't the issue.
In fact, probably it can never be cured - but YOU can do a
lot yourself to manage it. Sadly it's true that this is a disorder where it affects your normal behaviour.
You seem to read a lot about medications etc and quite intelligent. Stop worrying about searching for medications and start reading about how an adult could
manage ADHD. There are many resources on the web. These will help you to get organised and take control of yourself better.

Good luck !
