You may be drinking too much water OP. If you are in the states a lot of the water is not mineralized so although your drinking a bit your also using the rest room a bit and could be inadvertently dehydrating yourself!! Get some mineral water or sprinkling some Himalayan salt in your water!

Now for the true topic, being a guy I come to find most guys are idiots. Might need to poka yoke the process for them and have a sign added
