Not exactly a "former believer", however Adam Taylor, who has written a lot for the 9/11 Truth Movement is withdrawing from the movement, and closing his blog:

Interesting is his account of how he kicked the habit:
I think this kind of conspiracy fatigue is a way of exiting the rabbit hole for many people. While they don't give up their conspiracy beliefs, the lack of progress leaves them disinclined to do anything more about it. They don't need to watch conspiracy videos every day. They take a break, and when they return they see the movement a little more for what it really is - a stagnant mess of suspicion and contradiction - generally well-meaning, but directionless and error-prone.
