carbonation:it takes a drop to make it rise

Due to my bonehead "forget to add priming sugar to the beer before bottling" move, Nancy and I tore the caps off the Nukey brown and put a Cooper's carbonation drop in each bottle before recapping. After searching far and wide I discovered that the drops should take only a few days to add the carbonation needed. Knock wood!
After looking at the drops though....I wonder if I could've just used Lemonheads.
