Okay so I'm the one who ticked much improved.
I know up-thread I deleted my commentary (this forum upheaval business is disorientating) .. however my commentary is also in another thread which I can't actually delete now, so here's my full comment, originally posted in this thread:

Okay this goes with a disclaimer:
I am not medically qualified. Make of this what you will, but the following account is not medical advice.
I am not recommending any form of treatment, only telling my story as it happened to me.
I am just one person and, in terms of progressing knowledge, this story is only an anecdote.
So, I was on Viread, also known as Tenofovir for a year starting in late 2015. (I think this is the first time I've actually said this out loud in a public space, although there are probably a good few folk who know this already.)
Taking Viread requires regular kidney function tests, so needs to be medically supervised. I understand it has not yet undergone any formal trials in the context of ME, but that it has been approved for use in AIDS.
I have now been off Viread for almost a year, and with a few ups and downs, I have pretty much held the gains I achieved during that treatment year.
It took about 4 months on Viread for any changes to become apparent, but then I had a rapid increase in ability over a couple of weeks followed by much slower gains with some bumps along the way until the 10 month point. My physical ability peaked at about 10 months after which I had some decline. That decline appeared to be halted when I stopped the drug at 12 months.
I know of some others that Viread has worked for, but also those for whom it has given no benefit whatsoever. I did not combine it with any other drug, although from about 6 months in I took sodium bicarbonate to counter acid accumulation in my muscles.
Viread has not restored me to my previous level of health, but I now have much greater flexibility in what I can do, mostly due to a greatly reduced PEM response (although that has not gone entirely). Nor has my aerobic capacity returned to previous levels. I can now walk a reasonable amount, eg when shopping, but only by taking it slowly. No stomping along in a constant hurry as used to be my norm.
I should say I was horizontal most of everyday prior to treatment, and was slowly declining year on year - despite my efforts to pace carefully. For the 3 years prior to treatment starting, I was only able to leave the house using a mobility scooter, or wheelchair. My illness onset was in early 2012.
Why it helped me and not others is a mystery. I was one of the lucky ones it seems. I was also fortunate to have the means to pay for this treatment privately.
I know folk might think I should be actively promoting Viread as a treatment, but it's not so simple: I had some reactions along the way - such as increased migraine episodes - and I know others who had bad responses too. Although it feels like a miracle to me, it is not a miracle cure for all with ME.
Earlier this year I wrote a blogpost about my improvements - It was in the context of NOT needing any form of graded exercise therapy in order to take up my new found energy levels:

I hope that helps a bit.
