Not a nice subject to talk about but just wanted to check something. Been on exante only a week but man, I need to go and I cant! I drink 3.5 litres of water plus a couple of cups of tea - I cant possibly drink anymore water! Does this side effect happen for the duration or only while your system gets used to it? Also, can I take a laxitive to help me out, my tummy looks like I'm pregnant!
