It hasn't made me fuzzy at all, but it definitely is pretty calming, so if you anticipate major medical needs that are the type of "maybe go to the ER tonight or not?", this might not be the best thing. I don't know that I'd feel comfortable driving while still affected unless the roads were pretty damn clear. On the other hand, if it's not like that and more normal family stuff, I can't imagine this would be harmful at all.

It's certainly nothing like the z-meds (ambien, etc) that seem to zonk you out. This wears off pretty quickly and I don't have any sleep hangover.
