I've been making Kombucha now for quite some time and have in the region of 12 bottles in my cupboard. I am drinking a glass first thing in the morning before I get myself ready for work and before I sit down to a normal breakfast.
I do feel more awake and alert by the time I sit down to eat, about 20-30mins. By this time I have made my lunch for work and got the kids lunches ready too.
I'm at the stage now where I feel that I can continue with a glass before my lunch and evening meals so will begin that after I harvest my next brew as I am collecting a large amount.
I am having to ensure that I continue to drink plenty of water throughout the day though which can easily be forgotten as it is part of the success of Kombucha in removing toxins within the body.
