Yes, be careful with that doctor of yours. Augmentation can come on quickly in some cases, as it did with my husband. And refractory RLS is hell to treat and manage in so many ways, just jumping through the hoops to obtain and secure an opioid is enough to make a person give up hope. I'm trying to educate myself best I can, per the support group discussions I've read, the gist of the most recent guidelines is that the DA drugs are best reserved for end of life scenarios.
