Your symptoms do sound like RLS/WED. If you reach a point where it's effective and you're not up to the doctor's recommended dose, contact your doctor and ask if you can hold it there (since problems do ensue more frequently the more you take.) But I wonder if Mirapex is going to do the trick for you.
Your neuro sounds like he knows what he's doing as far as RLS/WED goes (not all do), so I assume he's checking your ferritin with the blood work, but please do yourself a huge favor and ask to make sure. Also ask for the results - not as "normal vs not-normal, but an actual number, which is nanograms per litre but that's not important, the number should be 50 and preferably 100 or more for people with WED, though 20 is normal for other people.
The reason ferritin is important, is that low ferritin is strongly linked to more-severe WED and to higher risk of augmentation. Ferritin is a protein that transports iron, and if it's low, that suggests that parts of your body might be low (like your brain, which is chronically low in iron for WED patients). There is some evidence that supplementing with oral iron can lessen symptom severity, and a recent report recommended that doctors avoid prescribing Mirapex and the other dopaminergic drugs to WED patients whose ferritin is <100. (Augmentation is a worsening of the symptoms in time between doses; an increase in severity, earlier time-of-day onset, spread to other body parts).
I take two 300mg tablets of ferrous sulfate daily (nightly) and if I skip, I notice it on the second day. My meds can handle the symptoms most of the time if I keep taking the iron.
Your best course of action right now is to educate yourself as much as possible on the disease, and treatment options. Also read about augmentation - it has been known to happen within days of beginning a drug (for me, 3 days on ropinirole), for other people years, and some people never augment. Reading people's experiences here will also help; some of the medication solutions being used by people who post on this board are not options that every neurologist or sleep specialist knows of. Don't ever think you're out of options!
