I read this earlier today and I know this is not referring to same condition as Sheila, but I wonder if the locum doctor who halved Sheila's dosage was maybe 'swayed' by Sheila's looks? Just me speculating...

That could very well be the case. It happens all the time, and not only in connection with mental illness. My own, very beautiful sister was a victim of that. She kept going to doctors complaining about stomach problems, kept getting sent home without even and examination of ANYTHING. This went on for years and finally she was sent to some examinations at a hospital. What happened there? A doctor made quite a direct PASS at her, she went home.
She got worse, and FINALLY she was diagnozed with a terrible cancer. She did receive monetary compensation from the state - but we lost her. She died.
And this is by far not the only example of this I know about! It is SO common. Beware of those docs. Most of them are no good!
That is terrible about your sister, Abs.
I know about 'passes' by doctors. When I was 18 in hospital, I apparently had a 'T.U.B.E.' ie a 'Totally Unnecessary Breast Examination'. That is how doctors themselves refer to it! I found this out a few years ago when I briefly dated a doctor and told him about it. I was so naive at the time but bewildered by it, which is why I mentioned this to my friend. So they are aware it goes on. Picking on the vulnerable as per usual.
I've not heard of TUBE but I know Doctors do have lots of codes they use amongst themselves. For example, if you find you have "NFT" written on your chart, they intend to let you die!
Please enlighten us (me) 
It stands for "Not for Twos". 222 is the traditional internal number for the emergency crash team, so if you're NFT it means they won't call the crash team if you have an arrest or seizure. To be fair it's done to alleviate further suffering for people who are already close to death, so a rather different intent than the disgraceful TUBE acronym mentioned above.
The most famous one, which many of you probably already know, is NFN, or "Normal For Norfolk" - used in a patient's notes to indicate to other doctors that they're a sandwich short of the full picnic, so-to-speak. I think it's fallen out of use now though as it became too well known.
