Naw, I do a coffee enema to stimulate the bile flow to my liver and that helps flush out the toxins making my headache and brain fog disapear. Exercising helps eliminate toxins from the lymph system as well. You have to make sure you are haing a daily bowel movement to get the toxins flushed out of the colon. Use an enema or herbal laxitives if you have to but elimination is key I've learned.
not sure if its the same but i have use activated charcoal both when drinking as a hangover stopper and for general detox and health. it does appear to work both instances to help me feel better, more clear headed and refreshed.
i have used a brand name (sobr'k), capsules from the health food store and also the charcoal powder. currently on the powder as its a lot cheaper but also more messy.
