Up to 2-3 years ago I was very healthy, except a few glitch (that I believed were minor) and very athletic and mentally sharp. Then a few things changed in my life pretty much at the same time, and there came a downward spiral. By now I have a lot of symptoms, but right now the one I'd like the most to fix soon is that I need to drink 10-12 liters of water a day, spread every half-hour, to be able to solve (academic) problems. It also keeps my memory fairly good (although not what it once was). If I dont drink for a while I quickly loose my focus/train of thought and remembering things become difficult.
It's the 4th time it happens to me in 13 months; the 3 previous times I drank my 10-12L a day for roughly 3 weeks and started to get somewhat better. But then I would reduce my water consumption and within months I'd be back to my confused state. Like currently I can even feel a bit dizzy, disoriented and the perceptions of things around me seem disturbed. I also consume electrolytes regularly (else at some point I get a bad headache, esp. toward the cerebellum).
I would point out that I pretty much never feel thirsty. In fact I pretty much never felt thirsty throughout my life, even though I remember as a kid I'd urinate very small volumes and quite dark color. However, when this occurs like right now I often feel very tired (even if I'm fully rested) and somehow drinking 1-2L quickly wakes me up.
Thanks in advance
