did you do a parasite program before the flush? Sounds to me like something that would happen if you didn't. If not, you may have stones still in your intestines causing some problems. Try an enema, as i was going to suggest epsom(1 tbsp) and 3/4 cup fresh grapefruit. Or you could try The Master Cleanse internel enema, which shouldn't be hard on your stomach, but for me is hard to get down, but flushes your colon out good. 2 tbsp natural uniodided Sea Salt , with 2 pints of warm water, all drunk in less than 5 minutes. In the meantime, be good to your liver with good herbs and foods. also, i hear apple juice, fresh organic, a week or few days before throughout the day can help soften stones.
