I'm trying to be healthy and drink enough water because at the moment I drink about 1 glass of fluids a day.
Yesterday I drank about a litre of water and it gave me splitting headaches.
Does anyone know why this might be? It always seems to happen when I drink water and I'm trying to lose some fat so I figure a good way is to make little changes like drinking more water.
Any help? It happens whenever I drink any fluids, not just water, which is probably why I don't drink anywhere near as much as I should.
