Want to know about oil

I am new to this web site and liver/gall bladder cleanse. My name is Amo. I am a woman in my late 40s. I have allergies. I take anti-histamine everyday. From time to time, I get asthma attack. I had Breast Cancer but was already cured in a hospital by an operation followed by 25+7 sessions of radiotherapy 7 years ago. I get sick (cold, flu and fever) very easily and often. I would like to try Liver Cleansing but I am very scared. I have 3 questions:
1) Can I take every day a bit of olive oil (30 ml.) mixed with lime juice (30 ml.) without a big day of fasting and taking more oil, lime juice and Epsom Salts . Which way will give me more difficulties? (Because I am scared, I do not want to take a lot of them and face that big day.) Can I just do it bit by bit?
2) I would like to know if I have to use only olive oil. Can I use cold press sesame oil instead? and
3) I do not know grapefruit. We do not have organic fresh apple sold in our country. All apples sold are imported. I am not sure about their quality. If I do not want to use lime (no lemon either), can I just use something sour? For example, pineapple, raw apple cider. We can buy raw organic apple cider in some supermarket.
Thank you very much for answers. Regards, Amo.
