If you feel good about the MC, then continue on with it. One thing that was recommended to me was to take things one at a time. For instance, I was advised to wait until I had gotten back onto solid foods before I did the liver cleanse. I also get really excited and want to do everything all at once also...
As far as oil pulling is concerned, it's best to wait until after the Master-Cleanse for that also. As I understand it, it can help stimulate the digestive system and one of the goals of the Master-Cleanse is to give your system a rest.
