Hey Davina Maria, have you tryed having a sports bottle and just having little sips? I got to week 3 first time round and then started struggeling so i switched to sparkling water and now i sometimes have to stop myself drinking lol Worth a try maybe?
As for the poo side of things, i dont know really, im the other way, i have to take laxatives twice a week just so i go!
What about that fibre clear stuff? Maybe that will help ya ask at the pharmacy see what they suggest.
