I tried the flush last night for the first time. I managed the Epsom Salts mixture at 6pm and 8pm but they gave me a headache and i felt pretty bad. I drank the whole glass of oil/lemon. I didnt feel sick at first but as i lay down suddenly vomitted the whole oil/lemon up. I do not take any citrus usually as they give me migranes but thought i would chance it as the cleanse will help relieve other symptoms. I think my body rejected the lemon juice. All that horrible taste, headaches for nothing. I am disapointed but hoping to flush out my liver/gall. Any advise out there??
