How many ‘Suddenlys’ are too many ‘Suddenlys’?

I’ve suddenly realized that I’ve developed an obsession with ‘suddenly’. There’s too much suddenly happening in the book: He turned too suddenly. She moved across the room suddenly.  It was suddenly dark. Suddenly, I realized. I felt that very suddenly. It’s a good word and everything – it really is – but my relationship with it has degenerated into something rather unhealthy. It’s a dependency, a crutch. And so I’ve put myself through a mini-intervention, used the dreaded search function and deleted and replaced. Now I’m suddenly down – damn it! – just down to, just down – no suddenly! – down to 21 for the book. I think that’s a good number. I mean, how many suddenlys do I really need? I suppose I could get it down to 15 or even 10, but what’s the point? It’s not like I have to go cold turkey on this. Right? (It suddenly got very quiet.)
