Restless Leg Syndrome is when your legs are restless when you lie down. There is medication for it though, but we imagine it causes excessive sexual desire and a gambling urge. According to Wikipedia the condition exists but according to RationalWiki it doesn't. RationalWiki thinks drug companies are pretending there is a disease called restless leg syndrome to persuade healthy hypocondriacs to pay for medicines they don't need. If you think you have restless leg syndrome then don't overwork also cut down on caffeine and other stimulants.

"Wouldn't it be better if you had a medication that stopped the gambling urge but occasionally caused [Restless Leg Syndrome]?"- Jon Stewart
