Read my message!!! Demerol and related opioid analgesics can kill you WITHOUT being combined with Eldepryl! For example, Demerol plus levo- dopa (good old reliable Sinemet, remember?) can be deadly. And don't trust me on this, it's emphatically stated in Duvoisin's book on PD. Cheers, Joe J. R. Bruman (818) 789-3694 3527 Cody Road Sherman Oaks CA 91403
