I don't understand but I'm not complaining. Week before last was 'the works', five relentless days grinding me down to a wretched state, but last weekend like a switch flipped. Spent the weekend getting strength back, since then no wind buildup and excruciating discomfort, I could get on with my life.
Been 'normal' for last days. In my wildest dreams I could not have imagined being able to drive 150 miles, overnight in a hotel and know I'd be able to drive back, also eat junk food with no obvious bad effect.
So it can disappear as soon as it arrives.
Why?
I asked my daughter to pray for me (you don't have to believe that, but I had a 'day off' after a similar previous intervention with absolutely no other change).
Last weekend I restarted on 15mg mirtazapine. But that previously never seemed to have any effect other than to give me vivid dreams. I honestly can't think of anything else significant.
Finger's crossed, not counting chickens etc, but if you're in the depths, there is hope, it can and does disappear.
This was sudden, but lets see if it endures. Last year it gradually died off and stayed off for best part of a year.
