Hello aussie-guy to much detox in a digestive tract can lead to bowl issues.Are you getting adequate fiber?Is your bowel flora,the internal garden in good shape?Are you drinking enough purified water?There has been cases of low blood preassure issues with grass juice consumption.Detoxing to quickley has changed the protocals of many healing retreats.Depending on the health of the individual detoxing can be irrelavant or deadly.How old are you are you on meds.what is your goal?There is much mis. and disinformation on wheatgrass juice.Grass juice has less than 1% chloraphyle by liquid volume.If the juice is giving you gass I suggest adding digestive enzmes to your diet.Are you growing your own wheatgrass?Is mold an issue?Good luck!!
