Help with Lupin's boggart

You know, while reading the posts about Lupin's boggart I thought it can't
be nothing else but moon. But know I'm almost sure that it can't be moon.
Why? (apart from the fact that I can't understand why he should be afraid of
the moon... after so long it should be a normal thing in his life...) I was
surprised that no one has came up with it yet (or maybe someone has?)

The orb which we see in a scene in PoA can't be moon because it doesn't
affect Lupin in a way real moon affects him. According to Harry's boggart -
Dementor, it (boggart) behaves in the same way as the real one. When Harry
sees his boggart he can feel as if the real Dementor was approaching. He
hears the voices in his head and so on... So why Lupin's boggart doesn't
affect Lupin? Why he doesn't change into a werewolf? It'd seem logical after
all... 

To me now it's obvious that Lupin's boggart isn't the moon. It simply can't
(as far as JKR didn't make a mistake). Now I'm questioning myself... is it
really the crystal ball?

It seems that Lupin is as complex character (or even more complex) as
Snape... Which not necesserly makes him ESE!Lupin...
