Confusing addiction with dependence and/or tolerance:
If tramadol relieves someone's symptoms, of course they'll become dependant on it because RLS never goes away. And a lot of medications, over a long period of time, will lead to tolerance build up, requiring the user to increase their dose to get the same effect. Addiction, however, causes abuse (or vice versa). There is nothing inherent about tramadol or RLS that would lead someone to abuse it after taking it for a long period of time. I repeat, needing to take it to relieve legitimate symptoms (dependence) or needing to increase a therapeutic dose (tolerance) is perfectly fine. Tramadol by itself will not cause someone to take more than necessary (or more often than necessary). That's abuse. That's addiction. And that's person specific.
