I've never had restless leg syndrome, but have had akathisia from certain (not all) antipsychotics. Do you know you have restless legs syndrome, and not akathisia? Or do you have both?
Forgive me if you know the difference well, but for anyone that doesn't:
"Akathisia and restless legs syndrome (RLS) share some common clinical features and a common relationship with dopamine dysfunction. However, the underlying causes and appropriate treatments for akathisia and RLS are different. " from
