It's very common for drugs/supplements to stop working with ME/CFS, that's just the way it is. Unless you are treating the root cause (which I don't think Abilify does) there's always a chance of relapse, but it doesn't mean it necessarily will happen. In any case, improvements like these are remarkable from severe patients and hopefully it will help researchers to get one step closer in understanding this disease.
I predicted months ago in post above that Abilify would likely stop working at some point. This isn't because I have some special insight, it's just the way it seems to be with ME/CFS treatments.
My own experience with new drugs is that there tends to be a honeymoon period, which for me is even shorter, a couple of days to a week. After the initial improvement, you either fall back into the "trap" or often times, you even end up slightly worse than baseline. I have also noticed the reverse effect. When I attempt to reduce dosage of, say, an antidepressant, I again start to feel better. This keeps repeating until I'm off the drug, at which point baseline symptoms return.
If I understood correctly, Martin was feeling best at the point when he was still in transition of increasing the dosage, which sounds exactly like the honeymoon effect. Since this happens with so many drugs in ME/CFS, I don't think there is necessarily anything unique about Abilify causing this. Similar tolerance issues seem common in for example epilepsy, one paper here describes some interesting hypotheses.
I really think the problem boils down to figuring out a way to understand and avoid this effect, but unfortunately I have yet to have any practical success doing so.
