How To Retrieve Erased Note?

Just trying to type more info at the end of a page and before I knew it I erased a very long note, can it be retrieved?. I cannot see an "undo" icon. Since I did a sync with iTunes after, not even the "restore" option might help. I hesitate to use it because it says that I'll lose all kind of info as well and I might end with the note still lost plus a bundle of apps and other contents. Very frustrating! Maybe apple should think of improving Notes. I thought it was something like OneNote, even in a simpler version, but I am sorry to say that it is proving less then useful. Maybe I should stop using it altogether. If things get erased for good this easily the program seems useless! Did not even ask for confirmation or anything, just lost!!!!
