How much water should I drink per day to be healthy?

At least 64 oz (or 2 litres), preferably more.

Michelle, it depends on your current weight and your current levels of exercise. My advice is to check with a Professional Nutritionist, preferably one with a degree in the subject, to see what they say. My Nutritionist recommends 88 ounces for me on a daily basis, but that takes those two variables into account. As noted int he other post 64 is recommended on a daily basis in normal situations, but other variables also alter that amount.

I aim for 100-120 oz and most of the days I get that. I am careful not to get too much, but not too little either. Following diet to lose weight can cause constipation, do drinking more water really can help with that.

It was told me 2 litres are ok

It depends on how much you weigh, as told by my surgeon. I've heard a few things, half your body weight or 60-70oz are the most I have heard.
