Glucose test was fun...not

So with my daughter I passed. I also had no Ill effects after drinking it. This time about 30 minutes in I got light headed and wanted to lay down...I wanted to poop too. I could feel the color draining from my face and then as quick as it came on it left! I was fine by the time they drew my blood for the second time. I only had 2 slices of buttered toast this morning so Im sure that had something to do with it...right? Just hoping I pass after all that! Anyone get side effects and still pass?
