I feel a little like I have the stomach flu, without any other symptoms: waves of uncomfortable nausea, sometimes feels like I'm going to throw up. Anyone else have similar experiences or advice on what to do?

I should mention that I'm trying for my first ever 7 day fast. I've done plenty of intermittent fasting, several 1 & 2 day fasts, and a couple of three day fasts. This is the first time to feel like this. The only thing I did different was to cut out sugar and carbs one week prior. I'm taking electrolytes, drinking water etc. I have bone broth on hand if I need it, but of course with my stomach feeling like this I don't want to ingest anything!

It's frustrating too because I can tell I would feel good otherwise, if it wasn't for the stomach queasiness... any thoughts?
