I used to do all that... just drink regular and snack often, its most likely dehydration and low energy levels... I used to sometimes get like that when I only drank at lunch and break time... then I would take like 3-4 litres of water to work with me in the summer... :P

Also... only have your dust mask on if you need it, if its a good mask... it filters some O2 out aswell which can make you slowly get light headed.
Yep. Flagging, asphalt patching, etc. (I'm trying to get my Class B's so I can drive the dumptruck mostly and get out of doing that aggravating work )

I started drinking a lot more, and I don't feel light-headed anymore. It wouldn't hurt to eat more, too.
