Absolutely and totally yes. Like you, mine sometimes seem to come out of the blue. It is so disorientating and frustrating forme; I just start to feel I am making progress and then I feel back in the valley. I have to keep thinking of it as a range of mountains I must cross, with many mountains to climb and many valleys to cross to reach the summit, but each time going a little higher up, with better views.

Know you are not alone.
