Overhydration or water poisoning – Tweek-a-Week: Weight Loss (Free) Review

Please don't ask your users to drink up to one liter of water first thing in the morning. It can be dangerous for people to drink too much water at one time, ever heard of hyponatremia? 1 liter might not harm most people but it will harm some, whose kidneys are just not predisposed to expelling so much in one go. At 2 or 3 liters of water in one sitting, as some enthusiasts of your app, are wont to do, it will be a serious and potentially life threatening condition.
