I need a doctor or someone to tell me what's wrong?

Anonymous
Last year, the doctor told me that my heart as early beats. I don't notice this or anything so I go on with my life. A few months after, I had an episode where I actually fainted. I didn't think much of it and went on with my life. Another few months pass, and it happens again so we went to the doctor. He tells me it's just because I don't drink enough water (which I should drink more, but I drink about 2 bottles a day). I play softball so when I'm there I know things are more harder to do than before..like all the conditioning. There has to be an underlying problem than "you don't drink water" can someone help me?
