I Have Had Hep C Since 2002. Have Been Through

I have had hep c since 2002. Have been through all available interferon treatment. Am a non responder. Have experiienced rigors before in the past but last night had the first relapse of them in over 2 years. In the past they have lasted perhaps and hour. Last night they lasted 4 1/2 hours and when they stopped I had a temperature of 104. I have cirrosis now but I am to begin a new threatment on November 4, that has very high sucess rate and is not an interferon treatment, no injections just a pill a day for 59 days. This bout with rigors took alot out of me...I am 61 years old. Is there anything that can stop them and what ever else you might convey to me with regards to this situation.
