Hi Jim,

Sorry can't help regarding Apomorphine.

Here we have levodopa under the name Madopar Rapid. Gives you a fast on.
In U.S. I think it's marketed as Liquid Sinemet.

If the liquid sinemet works the same way as Madopar Rapid as well as a fast on be warned it doesn't last very long and gives a fast off too.
Definitely worth a try though esp. in morning when you take your normal dose of Sinemet to kick start you!
