Congratulations on a great flush. With results like this, you should soon be feeling better with less pain. The process of decongesting a very congested liver can be quite uncomfortable. However, it is worth the effort. I wanted to comment that you have proved the adage of "less equals more" can apply to liver flushing. Like you, I experimented with various times of fasting and larger amounts of oil. I found that I did much better with 1/2 to2/3 cup of oil. Any more than that made things worse not better.
Fasting affects bile production. Your longer fasts may have reduced the amount of bile produced and lowered the pressure to help push out stones and debris. There are a lot of individual variations on what will work best. Regular flushing and experimentation will help you discover the perfect program for your needs.
