DISCLAIMER:
Before anyone misunderstands what I said and drinks a 55 gal drum of water
Once before coming to work I drank 2 huge oversize mugs of coffee at home. All during the day I drank water and juice. During my last break of the day I finished all the coffee in my thermos. Not once did I get a chance to go to the bathroom.
When I returned to the hub my kidneys felt like it turned to stone. When I got to relieve myself the stream was so powerful I thought I could have cracked the porcelain.
Sorry for the visual.
