Julia is a terrible doctor, of course, at least as written by the DS writers, who probably had absolutely no counsel with any real doctors and made everything up as they went along. I still remember when Willie was hospitalized after having 5 bullets pumped into his back (by Collinsport's finest). Dr. Woodard told Julia that if she disconnected his IV, Willie would die. I never understood that--it wasn't as if he was on life support and she was disconnecting an apparatus that was doing his breathing for him.
Even back then, as a teen, I noticed how half-assed the medical aspects of this show were handled--half the time, long-term patients weren't even hooked up to an IV!--but somehow, I dismissed or accepted it all, including Julia's insane actions. She was a woman in love, and somehow, everything else, including her questionable medical practices, was acceptable to me.
Love, Robin
