Nausea 24/7

Hi Mummies! I'm 5weeks 6days pregnant. 1st time mummy to be here. I've been experiencing nausea almost 24/7 and am puking everything that I'm eating. Was given anti nausea med by my OBGYN but it wasn't as strong as I hope it was - I still puked 3 times today. Any home remedies to help alleviate the nausea? Thanks in advance!
