For me a coke, diet or not only quenches my thirst while Im drinking it. Afterwards Im thirsty again. Beer has that affect as well. Give me good ole water to quench and thin my blood. Ill save the Coke, actually Sprite, to drink with lunch. Then a forced bottle of water right before hitting it again.

Both observations make sense when you consider that whether it si alcohol or caffine, your body has to use a lot of water to eliminate it from your system. In other words, caffenated drinks and alcohol both result in a net loss of fluid over the long term.
Alright, I am going to speak up here, back about 3 years ago I was diving Ginnie and took a good(bad) type 2 hit. Let me start off with some things that I know contributed to this, 1) Was dehydrated going into the dive 2) Was diving in a thin wetsuit, and became very cold on deco 3) Lifted 2 sets of doubles out of the truck and carried them to my shed in the backyard
I did not take the hit right away, it was about 6 hours after the dive that I starting having trouble feeling my feet. I first thought it was a pinched nerve or something along those lines, then my hands starting tingling in the worst possible way. About an hour after the onset of the symptoms I felt like someone was stabbing me with pins. I still tried to deny it, cause I felt it was embarssing to get bent. Finally I gave in and called Shand's hospital and told them that I would be coming in, the neuro surgeon met me in the ER and put me on O2 first thing. This helped me feel better in a few minutes, so he kept me on O2 from midnight until 8:00 AM. At the time the doc wanted to lifeflight me to Orlando to a chamber that was open, however I did not want to do this at the time and told him, just let me wait until morning. Shands chamber did not have anyone on call this night, for some reason. The next morning at 8:00 AM I was put in the chamber, and did not come out until about 7:00 or 8:00 that evening. I had to comeback the next day for one more ride, to clean up anything left over. I can honestly tell you that every deco dive I do now, the hit is in the back of my mind, therefore I add extra safety into the plan. CHAMBER RIDES ARE NOT ANY FUN!
Bottom line>>>> Make sure you have DAN insurance, you never know when you will need it.
Make sure you are well hydrated.
Make sure you use the proper exposure suit for the dive.
Limit your activity after a long deco dive.
And above all, If you feel you are bent, don't deny and seek treatment promptly.

Chad....THANK YOU for sharing your experience so we can all learn here. I wish DCI weren't kept such a secret, where we could learn more about it. What you're doing in sharing your story, is IMO a huge step towards understanding this mystery.

Several friends who are divers and also physicians have told me repeatedly that hydration must start at a minimum of 12 hours before diving, 24 is even better.
Drinking a bottle of water just before a dive cannot hurt but it does not do as much as many may think toward hydrating you.
Hydrate early & often.

someone may be taking this to heart
I spotted a 70 bottle in the cornflakes this weekend LOL

Regarding hydration, here's a quick overview:
Water equilibrates easily across all body spaces. Conceptually, we divide the water in the body into three compartments -- Intravascular, or what's circulating in the bloodstream; interstitial, or what's between the cells, and intracellular. Water is added to and lost primarily from the intravascular space. This is because consumed fluids are absorbed into the blood vessels of the gut, and fluid is primarily lost through urine production and evaporation into the air you breathe. Sweat can also be a significant fluid loss in hot, humid places (like Florida in the summertime). Intravascular volume can be lost and repleted VERY rapidly -- in the order of minutes. Anybody who has consumed a soft drink while driving knows this
Once volume is lost from the intravascular space, the water in the body shifts around to replace it. The first thing that happens is that water moves from the interstitial spaces, and then water comes out of the cells to replace THAT. These processes are slower, and occur over hours.
Intravascular volume depletion quickly elicits a thirst response, so most healthy people who are able to drink fluids and keep them down will not get to the point where they have lost interstitial or intracellular volume, unless they are in a heat stress situation where they just can't keep up with their needs. But in high heat and humidity, it does take a LOT of oral intake to maintain normal volume status.
So I would say that, in the absence of illness, excessive alcohol intake, or severe heat stress, hydrating the morning of a dive is probably completely adequate, since you are not trying to replete significant losses. But since there are few issues with generous hydration, making sure your fluid intake is adequate throughout the 24 hour cycle (especially with days of repetitive diving) is not a bad thing. If you are doing this in high heat stress conditions, considering a diluted electrolyte solution for part of your intake (1/2 strength Gatorade, for example) is not a bad idea.

lynne, what's the thought behind diluting the gatorade?
I wonder if most of these hits are type I or II?
Lynne, type II DCS (neurological) is the most common among recreational divers and neural fluids are one of the fastest tissue compartments (5 minutes, verses 2-3 minutes for blood). I have heard sooooo many recently complain that we are still "on-gassing" when we do those deep stops, when in reality we are sure to be off gassing the fast tissues (blood and neural fluids).
So, how does hydration affect the neural system? Is it considered vascular or interstitial in nature?
