Sounds like a blown head gasket if you can smell a sweet smell threw the exhaust.

No coolant leak on the ground overnight? If so, your water pump could be shot. Otherwise, as posted above it could be head gasket, but then you should have tan cloudy oil on the oil fill cap and lots of smoke out the rear exhaust.

The time I smell it is when it's overheating and I've got the hood open. Oil looks good. I did lose coolant the first time it overheated but I have ran it much at all since.

Ok, then make sure the fans are working. And the coolant system should be checked/purge from any air pockets. Also it wouldn't hurt to change out the thermostat.
