nice one, their are alcohol free bitters but their arent many uk sites.
i believe floradix is the maker of the alcohol free ones, otherwise you could use any bitter herb on the tongue such as gentian 30 mins before meals to stimulate digestive process and liver to cleanse. really working very well for me although i use grape bitters from vitacost which contain alcohol but the alcohol content is about the same as of a bananana.
adaptagen herbs are really helping me too, along with natural vitamin c and bee pollen to build up my adrenals.
sea vegetables are amazing too ive been getting some great success out of them recently.
