here are my 2 cent.
I would guess the olive oil plus lemon juice first thing in the morning induces contractions of the gall bladder and increases the flow of bile. And with it all toxins dump into your intestine.
Your wise body in turn is trying hard to get rid of all these toxins as quickly as possible by means of these impressive evacuations.
Frankly speaking I would recommend doing a full flush as quickly as possible. However, if your state is a little like mine before a series of flushes you will wake up the morning after the OO (Olive-Oil) drink being as tired as a dead body.
If this is the case - and I really want to stress - you MUST do enemas as quickly as possible in order to escort all toxins sitting in your guts out of the body. Even better would be a colema board. These cleansings of the colon should bring IMMEDIATE relief.
Furthermore, if your full Liver-Flush really happens the way I described it above you will have the key to a life with less fatigue and a better sleep.
I have now idea how old you are, but even without knowing this I would guess your should be ready doing a lot more than only 10 to 12 liver fluhses.
