Is it Possible to be dehydrated and not realize it? If so how (aside from thirst) would you know?

Sometimes we just forget to eat or drink enough, and dehydration can happen without realizing. Often thirst is one of the later symptoms of dehydration to appear. By the time we get thirsty, we can already be moderately dehydrated. Some earlier signs of dehydration are sticky or dryness of the mouth decreased urine output and dark yellow colored urine.
