Rumbling tum

[Sue9]

Hi I'm on day 8 and my tummy hasn't stopped rumbling. I have 4 ltrs of water a day and I don't feel hungry I just can't stop the growling/ rumbling noise. It's getting quite embarrassing. Anyone have any ideas why this is happening and if there is anything I can do to stop it

It's odd but the more I drink the more this happens. If I only have 2L I don't seem to get this. If I have 4L my tummy goes wild.
