I have had some success in doing another Liver-Flush when the first flush did not relieve the congestion. I would wait a day before doing it. In other posts Telman has advised not eating and taking another dose of Epsom Salts .
There are balanced electrolyte sports drinks and one person found a balanced electrolyte powder in a health food store. I just sprinkle a little salt and potassium chloride in a glass of water and drink that mixture until I feel better. I think that Sea Salt has a little potassium in it.
