You can use any sugar you've got in the house. Table sugar, brown sugar, even honey (but you'll need a little less table sugar, more honey than you would normally use of corn sugar).
See this link for info on how much to use of various sugars.
If the beer is already in the bottling bucket, boil up the priming sugar in water as usual and then add it and stir it in GENTLY.
If you've already filled bottles, I'd open those and pour them back in GENTLY.
Try to avoid splashing/bubbling which will oxidize your beer. Good luck, RDWHAHB.

The cans of Leinenkugel's had masking tape on them with JOHN'S printed in ink. Amy looked around me and said, "John is protective about his beer, isn't he?"
