Hypersomnia , sleepy , weak limbs .

嗜睡、困倦、四肢无力.

This symptom is particularly obvious in narcolepsy and hypersomnia .

这种症状尤其明显，在嗜睡症及睡眠过多。

While most insomniacs somehow manage to drag themselves through the day and function at acceptable , although not optimal levels , this is not so for people who suffer from hypersomnia .

对于失眠者在白天用某种方式逼迫自己在可承受的范围内运转，尽管不一定是最佳状态，对于嗜睡者情况就不是这样了。
