chest hurts is not good to hear as anemia can cause cardiac problems. I feel for you badly. You should have been afforded a better chance the first time around. I hope the increase works, truly.
I would not try a 3rd time.
I also admire your courage keeping the fight at that low hemoglobin level. As far as continuing on, if I remember you're a stage 1, geno 1? If the biopsy is recent, that means you have very little liver damage and could go off treatment for a while without much potential harm.
Remember, the whole idea of treatment is to more good than harm. A stage 3 or 4 might correctly risk the whole bank for a cure. A stage 1 has to consider more what the side effects are doing to them.
That said, there's one drug in trials right now that sounds perfect for you. Especially, if you end up re-treating soon. It's called Viramidine and replaces ribavirin. They think it works about the same but without the anemia.
And then, 3-5 years down the road are the newer drugs all of us are cautiously excited about.
I am a relative "newbie", but it seems to me that you could be doing more harm than good with this protocol. A 7.6 gm hgb is pretty dang low. If you really are just a stage 1, you may be able to wait for something less hard on you.
Take care of yourself.
