Southern Belle is definitly the vet of all this. But if the fever lasts you need to do something. I wouldn't wait a couple of weeks when you have a fever. I am one of those people who almost never goes to the doctor but even I would go if I had a persistent fever. Especially if it's being caused by such a vital organ. I agree that it would be good if you could wait a couple of weeks before flushing again but in the mean time you ought to go on and start killing the parasites. I don't think she meant that you should wait on the parasite cleansing. If you think she does then you might want to directly post a new question to her and ask her that specifically. Just in case I'm wrong.
