Thanks everyone! My little girl is 3.5 months. I've had her sleep in her little bouncy chair in the lounge and have slept on the couch next to her, and she's only been waking up about 3 or 4 times between 7pm and 7am (which means I'm starting to feel more human again with getting more sleep!)

For her reflux, we're giving her Zantac plus a homeopathy mixture plus she's getting treated by an Osteo. One of them (if not all!) is starting to help, and the screaming is slowly being reduced, and we're seeing more smiles from her again! (Yay!)

I'm thinking she doesnt like her bedroom for some reason. When I take her in there at about 6pm for her wind-down at the end of the day, she starts crying and becoming sooky! I've never left her to 'cry it out' in her room (which, I've heard, can make a baby have bad associations with their room) or I don't recall anything bad happening for her in her room, so don't know why she does it. Soon as we bring her to the loungeroom, the crying stops! Maybe she just likes being where the action is?!!
