Mostly green tea as that prevents the little sea anemone tentacles (lol sorry I cant remeber what they are really called ) in the gut, from shrinkinking down to nothing, from no food.
I am about to get some ginseng as well as a couple of other beneficial supplements I was reading about the other day.
I am usually over hydrated, I add a half teaspoon of pink rock salt to my drinks apart from occasionall booze and coffee lol thats just 33% cream in that.
Its normally around day 5 or 6 that I start to get the low blood pressure, other than that I donāt experience any other symptoms, other than hunger for an hour or so around my normal, once a day eating time, and reduced stamina doing manual stuff. I just pace myself better to compensate.
I eat mostly vegetable curries which have copious amounts of herbs and spices, vits and minerals, but still supplement vits and minerals, especially when fasting.
