Will try to give you some ideas for your upcoming visit. First a little info on Zopiclone (which I am sure you have already seen):
[/Zopiclone, a cyclopyrrolone derivative, is a short-acting hypnotic agent. Zopiclone belongs to a novel chemical class which is structurally unrelated to existing hypnotics. However, the pharmacological profile of zopiclone is similar to that of the benzodiazepines.
In sleep laboratory studies in man, zopiclone reduced sleep latency, increased the duration of sleep and decreased the number of nocturnal awakenings. . The course of treatment should be no longer than 4 weeks in duration.
Adverse Side Effects
The most common adverse reaction seen with zopiclone is taste alteration
CNS:
somnolence, asthenia, dizziness, confusion, anterograde amnesia or memory impairment, feeling of drunkenness, euphoria, nightmares, agitation, anxiety or nervousness, hostility, depression, decreased libido, coordination abnormality, hypotonia, tremor, muscle spasms, paresthesia, speech disorder.
As you see this drug causes paresthesia instead of eliminating it So I am sure it exacerbates yours!!! Also hostility as you noticed.
The algorithm for RLS treatment for your fairly severe RLS suggests the treatment with one of the dopamine agonists (e.g. Mirapex). Your RLS appears to be beyond the stage where only hypnotics would help. Especially not with a hypnotic such as Zopiclone with its side effect of paresthesia!
Codein based pain killers should help but possibly Ultram would be more effective.
Ask your doctor to take you off Zopiclone mentioning the fact that paresthesia is one of your major morbidity right now and Zopiclone happens to have this side effect so it probably exacerbates yours. (Sonata may be better if you need help to sleep.)
Getting rid of paresthesia might help you to sleep w/o a sleeping aid. To do this Mirapex may just be right for you. Mention to your doctor that Mirapex helps up to 90% of patients with RLS!!!
So ask your doctor's opinion to change from Zopiclone to:
Mirapex (titrated up from 0.125 mg/day)
Ultram for pain
Klonopin or Lorazepam for sedation (to get rid of stress)
or something similar to this.
First you have to calm down, get rid of paresthesia, treat pain, and then I think sleep will follow.
Let me know what your doctor thinks (or you, for that matter).
