During the inquest of Sheila,,I noted that Anafranil hadn't been present in her system. This was increased from 10mg a night to 30mg,,and is an anti-depressant. So you have to also question why Sheila wasn't taking that as well as the Stelazine ( anti-psychotic ) then the Procyclidine ( which counteracts the side-effects of the anti-psychotic medication ).
Only the remains of the Halpol was found in her system,,which takes medication 72 hours to clear through. So besides there having been a reduction in the intramuscular injection,,Sheila had not taken any of the other prescribed medication. A definite recipe for disaster,,which Sheila knew,that if she didn't adhere to her regime of medication,then her illness would have returned with a vengeance.
