first of all I would really like to encourage you getting an enema kit. It does not cost a lot and giving yourself an enema is really easy. Try it and you will see how helpful enemas are in particular for INSTANT relief of bloating.
I dissolve AC in about 200 ml of water. Be careful because AC can mess around and black spots on clothes and furniture are difficult to remove.
This olive oil:lemon juice mixture is sort of a "mini flush" I practise this quite often and it gives me a great start of the day. Two tablespoons of each should be sufficient. People in Kreta known for their longvivity - by the way - drink a small glas of olive oil first thing in the morning every day. So nothing is really new on my recommendations.
All this is a matter of trial an error. I can tell only about my feelings and experiences and what is good for me. Altogether , my digestion works a lot better with this olive oil drink in the morning and made it very clear to me what Andreas stresses all the time: Bloating, Candida, heartburn and bad digestion have their origin in the liver. As long as there is enough bile flow there is no bloating, no Candida , and no digestion problem.
Regardless whether you choose the castor oil option or AC you can eat afterwards. However, castor oil means taking a day off an stay close to the bathroom. AC in constrast does not interfere considerably with your daily activities. This is the reason why I like the AC method.
