Used to drink a crap-ton of kombucha. Tried some in the first week of the diet and set me back a couple days. I did use the cranberry version though – even though its very low in sugar it was extremely sweet after giving up sugar. You might want to try to the ginger, that is the only one I ever had that helped with digestion or made me feel ‘good’. It can give you a slight alcoholic kick if you’re sensitive to alcohol.
