I probably don't drink as much water as I should, though don't do too badly compared to many. However 3 things I want to improve are my skin (generally not too bad spot-wise but want to look more glowing and less tired), my energy levels (i have an 18month old and a 3.5yr old so am constantly shattered, just don't want to look it!) and finally i want to lose some weight - I know this will require better diet and exercise but I think I've read drinking more water can help too? Does It really make a difference to any/all of those 3?
