dizzy symptons are also common. Try drinking Crystal Light if you don't enjoy water.

The symptoms of dehydration are a dry or sticky mouth, low or no urine output (urine is dark yellow), not producing tears, sunken eyes, rapid heart rate, low blood pressure, muscle cramps, no sweating, dizziness. You need to increase your fluid intake, water, juice, clear broth, jello and stay out of the sun until symptoms subside.

...dizziness, clamy skin, you stop sweating, you are not thristy, dry mouth, yellow, yellow urine...take cover immediately and drink water, gater aid, power drink, just hydrate immediately... lay dawn and keep drinking...eat a whole watermelon...that will do the trick. I know. I had to do it or go in for an IV.

I heard that if you have a headache, you are probably dehydrated.
