For anyone on RLS medication, augmentation is always a concern.
I've been on Ropinirole for several years and have developed a regime that has so far avoided augmentation. I can't be sure it's ALL down to the method I use, but I'll share:
I use Ropinirole in chunks of several weeks on, several weeks off. Toward the end of each "on" period, I up the dose for a few days, then stop. I don't get cold turkey. In fact I find the benefit I got from the drug usually continues for maybe a week or more, then my RLS returns, but at a low, manageable level. It stays like that (with occasional bad days) for a few weeks before I feel it starting to get consistently bad again (ie several nights in a row of bad RLS) - and that's my signal to resume dosage, and it always works when I go back.
It's not perfect as you will still have to put up with occasional bad nights, but I always know the Ropinirole is there to release me eventually.
I'll add that this is not a physician recommended regime, I came up with it through trial and error and experience.
Hopefully this may help others.
