You may inadvertently have linked two unrelated events. I might ascribe your urpy stomach to something you ate earilier rather than walking thru the RT. I might also ascribe the queasy to some possible smell in the RT. Did you experience any headache? Did you open the refrigerator and smell anything "off"? Once, before vacating an apartment I turned the frig off but left green peppers inside and when I went to clean the frig a couple days later I almost threw up from the gas given off by the peppers, altho I couldnt actually smell anything rotting.
