This is what I did:  If, for any reason, she woke me up before the
alarm, she was put out of the room, the door closed, and we would
ignore any and all cat noises from the other side.  No response,
positive or negative.  Fortunately, Meep isn't a yowler.

Consistency!  We did this every time, it only took her a couple of
nights to learn, and about two weeks before she completely quit trying
to wake us.  She learned the "don't wake her up before the alarm" so
well that if I woke a few minutes before the alarm, I'd see her
sitting attentatively at the side of the bed, and she'd jump up the
*moment* the alarm went off.

She's also learned that she's not allowed above the waist on the bed
without permission.  Mostly gently, but unfortunately I tend to wake
and flail blindly if I'm woken by some sort of tickle on any exposed
skin - remenents of a spider phobia, probably.

A long time ago I read a post where someone did this, and kept the
vaccum cleaner ready in the bedroom...if the cat made a ruckus on the
other side of the door, they'd turn on the vaccum.  Haven't tried
this, but imagine it'd be effective, and might train your cat faster,
at least if it's afraid of the vaccum.

Any day you learn something isn't a total waste.

Cats are "pride" animals.  So as long as she is an only cat, you are
her "pride".  Perhaps a companion would help the situation.
