Glaze Color

I did the glaze color today on my bathroom (and garage for practice) walls. My head is pounding and my right cheek is strawberry red and hot. This is what happens! ANY exertion what-so-ever does this. The glaze color on top of the base doesn't look that good. It just looks sloppy. I'm wondering now if I should just paint it all white again and start over. Can you do that though????? Keep painting over coats over coats over coats?? Wouldn't that make the room eventually smaller? :-)
