Ginger tea works like a charm for me I make 2 cups of it and keep it by my bed. The instant I feel even a twinge of nausea, I take some sips.

I did my fifth flush this weekend and woke up in the night and threw up all the olive oil mix. Usually I have a cup of ginger tea before bed (after the OO) but didn't have any this time. I've never been sick on my previous Liver Flushes so I think the ginger is a must for keeping away nausea for me. And as it's been used as a natural cure for nausea for thousands of years, I don't think you can get much better than that!
