hey Miah, one of the side effects from your treatment, is shortness of breathe. and yes, the riba is the culprit.
reading thru your post, i dont see what your liver status is. did you have a biopsy, or other staging test done?
your dr will re evaluate your tx, to see if you have other options, or if everything will be fine. Either way, you will be fine. you are treating in a favorable time for Hep c. so many new weapons coming out for everyone, regardless of genotype, to snuff out this beast.
keep the faith Miah,
