Those are some good points you raise Tomas.
I don't know if there are any good research statistics on this (I've never come across any), but I doubt there's any argument against living healthily giving your body the best chance to defeat this virus.
But (and there is a but), following a particular lifestyle does not make a given in how your health will end up. Taking myself and the people I know (sure, anecdotal) I drank like a fish, probably to the point of alcoholism, for over thirty years (having hepc throughout) until I stopped a couple of years ago. I also always ate what I wanted and have been overweight to varying degrees for most of my adult life. On the plus side, I've always excercised well, kept fit, and since I was diagnosed with hepc about 13 years ago I have taken high daily doses of curcumin and milk thistle. My bloods before starting treatment last September were similar to yours (apart from a high GGT of 357), and a fibroscan I had last November gave a 'normal' reading of 4.7. Whilst I would not advocate anyone, with or without hepc, following my lifestyle, I have pretty much got away with it.
My brother, who has been an intravenous drug user on-and-off throughout his adult life and drank moderately when off the drugs, started suffering liver failure over 10 years ago and had a liver transplant about 2 years ago.
A mutual friend, who used intravenous drugs with my brother briefly over 30 years ago and drank and smoked fairly moderately afterward living quite a healthy lifestyle, died from liver failure over 5 years ago. He'd stopped drinking and smoking 4 years before he died.
Another mutual friend, who also used intravenous drugs briefly with my brother in the early days, has drank and smoked heavily for the rest of his life but otherwise kept fit and looked after his weight. He's still doing ok health-wise.
The point I'm trying to make is that, whilst you're right about looking after yourself, it's still something of a lottery. And living a particular lifestyle certainly doesn't preclude one from getting cleared from hepc.
Sorry if Doc James and Myself appeared to take your thread offtopic with our exchange, but there was an important point in there which addresses the point raised in your last paragraph. I've always tried to have a positive outlook and live my life to the full, and I've thoroughly enjoyed it so far. As Doc James said, the future is always a book full of empty pages in which one has the ability to write many different stories. And we do try to keep a sense of humour on this forum

Anyway, thanks for the thoughtful post. It made me think about a few of my perceptions, for sure.
