Everyones so sleepy

I will preface this by saying we got a carbon monoxide detector and we're gonna plug it in tomorrow. But, ever since we got our car worked on, it's been making the garage smell like gasoline or like, other car fume smells, and now everyone in our house is kinda constantly fatigued. To be fair we all suffer from chronic fatigue issues but it's weird for ALL of us to be experiencing it at the same time.

There better not be a leak that's so inconvenient...it feels like every time we get our car worked on it comes back with more problems
