Steve,I remain convinced that Sheila had had PPP. Because the condition hadn't been diagnosed and instead schizophrenia had,her medication would have been different too. Also,to have had the illness for 6+ years would have required a more lengthy stay in hospital and most certainly adjustments made in her medication.
Although the Haldol had been reduced, it would have meant also reducing the doses of her other medication to counterbalance the side-effects ,but I don't remember reading about that. However,when a patient takes such a high dose injection of Haldol which Sheila was originally prescribed,it tells me that the patient was/is " severely " ill,otherwise why prescribe such a high dose ? Yet Dr Ferguson had insisted that nobody had been in any danger ? That being the case,why the high dose ? What wasn't he saying as opposed to what he did say ? I just believe that the Haldol exacerbated the condition that Sheila originally had. It's a dangerous drug when administered for the wrong reasons.
Sheila had anxieties as well as low social confidence,which was probably why she took cocaine at parties to give her that confidence.
