My husband experienced a greater sense of taste after he started OP. Mostly likely, a lot of crud has been cleaned from the tongue, making the taste buds more able to do their job.
The pimples may very well be a detox symtom. Hopefully, they won't last long. Shortly after I started OP, I had two nasty boils on my tongue, all part of the detox, so good in their own way.
The longer you stay with OP, the more sinus relief you will have. My daughter-in-law says the days she skips pulling because she doesn't have time, her sinues aren't as clear.
Expeller-pressed and cold-pressed are basically the same thing.
Coconut oil is great, too, for pulling.
