Can I ask which oil you used. It is not uncommon for the oil to get thick and it is actually supposed to get white. It is probably removing a lot of junk from your system, which is a good thing. If the thickness is a problem, try a thinner oil like VCO. And don't worry if you can't go the 20 minutes in the begining, it will get easier the more you practice. It is well worth persevering and in no time you will be hooked.
