Take Liver Cleansing products for a longer term. With my Chronic-Fatigue-Syndrome caused by protozoa I have been on liver cleanse products for over 2 years. The liver is always overtaxed in this toxic environment especially with pathogen burdens. I use Buplernum combination from Planetary Formulas and add phosphatidylcholine with liposomal glutathione and methylation supporting products. You can add acupressure liver points (see Acumedico.com)for charts. You can rub out the points or use an Acupen from ebay, if the points are sore (liver points) it is probably an indicator of an overburdened liver.
The sluggishness is probably coming from toxins... up doses of antioxidants. Use some ascorbates (buffered vit C) - I take 10,000 to 20,000 mgs per day - use to bowel tolerance and split the doses up during the day. I have tried so many antioxidants and vitC has always been very good to me.
