Ugh, yes, very much. I find I can't read too many Heyers in a row, because it becomes overwhelming -- I start being unable to ignore the way that the books are all about one very particular class of people and NOBODY ELSE MATTERS. I do find the society the books are about to be a very fascinating one, including with all the stultification and repression, but the way Heyer often seems unable to recognize the ways that it is horrible gets frustrating after too many books.

But as long as I read enough other things in between Heyer books, I do find them extremely enjoyable! (though some are certainly less wonderful than others.) It's dangerous, though, because reading one puts me in the mood to read more IMMEDIATELY, and I just know that's not actually a good idea...
