You are already more diligent than I am! I don't track my water intake. I do carry a water bottle around with me 24/7, so I know I get enough. I also don't track calories, btw, just carbs. To be honest I am a bit anti-calorie counting, even, but my endocrine system/ metabolism is so broken - it's impossible to ask my body to adhere to the calories in-calories out math. If I eat too many carbs, I feel like shit. If I keep the carbs low and complex, moderating simple sugars in my diet, and stick to high protein, high (high quality) fats - my body is happy. So that's what I do.
