I already workout 5 days a week, I've been power lifting with some old Corps buddies for a little over a year now, so I don't think thats a problem. And I doubt it's dehydration because I have a strange obsession with water, so I drink 3-5 gallons a day
In addition to diabetes insipidus
as a possible issue, you might consider hyper hydration
. By drinking large amounts of pure water and failing to replace electrolytes lost to sweating, you may dilute your electrolytes to the point that your nerves begin to malfunction.
Seek medical advice.
It could be almost anything.
Seek competent medical advice. Maybe a sport medicine specialist.
Why Drinking Too Much Water Is Dangerous
, also known as hyper-hydration, water poisoning, or overhydration, is a potentially fatal disturbance in brain functions that results when the normal balance of electrolytes in the body is pushed outside of safe limits by over-consumption of water.
At the onset of this condition fluid outside the cells has an excessively low amount of solutes (such as sodium and other electrolytes) in comparison to that inside the cells, the fluid shifts through osmosis into the cells in order to balance its concentration. This causes the cells to swell. In the brain, this swelling increases intracranial pressure (ICP). It is this increase in pressure which leads to the first observable symptoms of water intoxication
: headache, personality changes, changes in behavior, confusion, irritability, and drowsiness.
