It isn't Charlie Boy.
I'm going to go out on a limb.
The Witches of Eastwick has a voodoo doll made of wax at the end. The three titular witches use it to try to kill the Devil (Jack Nicholson). There were some earlier scenes where the Devil cursed the witches and another woman. IIRC, there was plenty of doubling over in pain and puking up what looked like candied cherries.
No, i watched this movie in grade school with the boy next door..and well i've not got much time left being on the backside of thirty.. it would have had to have been made either early eighties or possibly late seventies.I do remember a big lady that looked like Mrs. Buttersworth too.
anyways, thanks for all the help guys..
