I was in the hospital last night thinking I was going to die. I had pressure on the back of my head that was causing me to spasm out and pass out. This had been lasting for three days. I was afraid to go to sleep because I was afraid I wouldn't wake up the next morning. I was sure that I had a brain tumor or the golfball cist on the back of my head had finally gone malignent. I had been doing normal activities and had been drinking plenty of water and working my job. Apparently I didn't realize that 8 glasses of water might not be enough for everyone. We found out that for the last week or so I have been slowly killing myself with dehydration because I haven't been drinking enough fluid to compensate my activity even though I had been drinking constantly in between breaks and drinking the required "8 glasses of water" So I just wanted to let Pfers know to please drink your water and gatorade!
