yea me too. almost had a nuclear meltdown in my shop a couple nites ago. was cleaning the motor in a screwgun using a product called electra motive or something like that. i only sprayed out a little, next thing i new my head hit the bench, and i didn't know what the heck was going on, or even where i was. immediately i shut the heaters down and threw all the doors open, went outside and sat in a snowbank in sub zero weather till my head cleared up. apparently the fumes from the motor cleaner crept along the floor and got sucked through the heater and morphed into some kinda deadly toxin. iv'e used the stuff many times before, but let this be a warning to all. i think carb, brake and electric motor cleaners can be deadly under the right conditions. wonder how many brain cells i lost on that one.
