I think most nutritionist/dieticians recommend at least 2 litres per day when not pregnant but the amount you actually need probably does depend on your size.
I have found that I am drinking a lot more - like heaps - and more healthy stuff (no coffee and now I'm even going off tea too ). I go by the colour of my urine. It's not really possible to drink too much water. You would be absorbing it because most of our bodies are actually water and we need a lot more fluid to make a baby - extra blood, cells, amniotic fluid, mucus etc etc. It just feels like it's going straight through you but its really just that your bladder is getting full. Most people have the urge to wee when their bladder gets to about 250-500ml but it can actually hold a couple of litres. Of course, everyone is different in this area too. Sorry, guess there are no definites! HTH.
