more than I used to

[navi]

Are all of the following sentences correct?
Do they make sense?

1) I didn't need money anymore, and yet I worked more than I used to work because I needed money.
2) I didn't need money anymore, and yet I worked more than I used to because I needed money.

3) He had lost all the money he inherited, so he worked more than he used to work because he needed money.
4) He had lost all the money he inherited, so he worked more than he used to because he needed money.

Gratefully,
Navi

Yes to 2) and 4).

No to the other two. They're not incomprehensible, but the unnecessary repetition of "work" is clumsy.
