I can only tell you what has helped me... I have been in a bad place with liver cirrhosis and chronic fibromyalgia symptoms (aching body, fatigue, visual disturbances, liver pain), and unable to flush due to scar tissue, but there are some things that I think are SUPER important whenever we are cleansing our livers... Beyond the typical recommendations for milk thistle, stone breaking herbs etc. our liver is profoundly complex and needs the right nutritional support.
I highly recommend liposomal glutathione. It works. Also 1/4-1/2 tsp tumeric (make with coconut oil or some kind of fat plus black pepper) to control inflammation in the liver from the stress it is under. Glutathione is a powerful antioxidant and will protect the liver from damage from recirculating toxins, while promoting detoxification and it is safe even for very toxic individuals.
Also, raw egg yolks. I have only just started drinking four raw egg yolks a day (gently whisked into nut milk) and it makes my liver and digestion feel a lot better and my energy levels and vision have improved dramatically. Eggs contain choline. Our livers need choline. Some liposomal glutathione supplements also contain phosphatidyl choline. Superb stuff which we need when we are cleansing. Use organic free range eggs and there is nearly no chance of salmonella poisoning.
Make sure you are getting enough b12 (liposomal vitamin b is best), and magnesium oil is awesome. I rub it on my liver and it's excellent. Magnesium taken orally isn't retained in our bodies for long and isn't as easily absorbed apparently. I used to use Epsom Salt and magnesium pills and never experienced the benefits that I do from the oil.
Lastly, oceans alive 2.0 marine phytoplankton is profoundly powerful. I can only tolerate 1 drop twice a day (not 15 drops!) and it contains everything the body needs to regenerate and build healthy tissue. Great for supporting a Liver Cleansing regime. The guy selling it had liver disease and recovered using it (apparently). It is a powerful detoxer also, so start slow.
Also, stick to complex carbs (rice might have spiked your blood sugars too much, I ALWAYS have a "carb coma" after eating rice or bread).
