My restless legs (driving me nuts!) is definitely triggered by low light levels (evenings, night-time, cinema etc) and eased/solved by staring at bright light from mobile phone (brightness on full) laptop (ditto), and my daylight spectrum SAD lamp. Takes a few mins to kick in. Something to do with melatonin/dopamine balance at low light levels I suspect. Domestic light bulbs have a yellowy light and you'll need a bluey light for this to work. Anyway, worth a try?
