I don't think that word means what you think it means...
Sleep apnea? Is Wikipedia like, restricted in some countries, or something? How about WebMD? sleep apnea, night terrors, and sleepwalking are three completely different things. They aren't even *related*, except possibly under the extremely broad umbrella of generalised sleep disorders.
If whomever wrote this script has a pill for sleep apnea, I want to invest. Just saying.
