What about Drow? They get kinda sick in the sun, don't they?
Not really. Drows usually live in Underdark, so they are used to darkness. If they go to the Surface, they just have to get used to the sun and they are fine. This is what happened to Drizzt - after leaving the Underdark he was "blinded" by the light but after some time it was normal to him. It's as if you are in your bed in the darkness and someone suddenly turns the light on.
