Can liver flush stir things up and make you feel worse especially when you have low hormones to begin with?

I am not a fan of the Liver Flush that uses large doses of Epsom Salts because it can deplete body electrolyte levels. The fact that you are slim and a vegetarian also hints that you may not have a lot of reserves in your body and Liver Flush (or any extreme cleanse) will further deplete your body.

My advice, eat plenty of nourishing foods and add a good amount of fats to your diet. Add a good amount of natural salt to your diet, especially if you do not taste the salt very much in your food. You also need a certain amount of other electrolytes, mainly, potassium, calcium and magnesium. Include plenty of foods that are natural sources of these elements and you should feel a great improvement. Even if a blood test says everything is fine, in my opinion this is not conclusive because your body has all sorts of other fluids that need to be balanced as well.
