How important is drinking water? I am 90kg and am struggling to drink 2 litres of water a day especially after two large babies I struggle with my bladder and am often out and about with no access to a toilet for long periods of time. I do hAve three mugs of earl grey tea a day too, but not sure if they count. Have been low carb ig for 10 days and have lost 6lbs so far. I keep my carbs below 20 grams
