It's a superb anti-drug song, and comes directly from Buffy's own struggle with Codeine addiction when she was quite young. She kicked it...with great difficulty. The line is definitey "My belly is cravin' (or a-cravin'), I've got a shakin' in my head" and later "you'll forget you're a woman, you'll forget about men, try it just once and you'll try it again".

The song is usually played in DADGAD as far as I know...or possibly double dropped D, but I think it's DADGAD. She did a lot of stuff in that tuning, as did the young Bob Dylan.

I still think it's the best anti-drug song I ever heard.

I figure that Buffy deliberately changed the spelling to Cod'ine, leaving out the 'e' in codeine, so that she could give the song a sort of spooky, unique title and get more good rhymes for the ends of the lines at the same time. It would not have worked nearly so well if built around the word 'codeine', because 'een' doesn't rhyme so handily as 'ine'.

That's sheer good songwriting instinct, not an accident. The apostrophe in Cod'ine indicates that she was well aware of the actual spelling of the word.
