Stop removing line breaks inside <style></style>

I have lost my support email I paid for so I will just post this here. If you could contact me with the email I would appreciate it.

I have a lot of code between <style> … </style>, and CKEditor is removing all formatting such as line breaks and spacing. I don't know if it does this when I save or when I re-open the file. (I am using Drupal.)

I need the formatting, and I know you can tell CKEditor to leave it alone, but I can't figure it out.
