Your favorite and least favorite meds to prescribe, including combos?

I had a challenging relationship with my dad, a psychiatrist, who passed away recently. Somehow I find myself more at home here in this sub (been browsing a lot) even though I'm a psychotherapist and not a psychiatrist. I'm a therapist, much to my dad's dismay, who wanted me to follow his example and get a medical degree.

In fact, I aced the MCAT, applied to Ivy League Schools, got interviews, but then last minute changed my mind, and went into psychology research and more recently switched to therapy.

Last night I was thinking about my dad's dislike of polypharmacy and low-dose quetiapine (added to the mixture just for sedation/sleep, like "extra salt" added to every recipe, no matter what, he would say). But I don't think he ever told me what medication he likes prescribing. I have this memory of him saying good things about olanzapine along with clozapine. And perhaps me arguing with him about how he could like a drug that causes so many severe side effects. It's all foggy now.

This intro is for my own benefit really, as my question does not need it, but recently I had a client complaining about a "stingy" psychiatrist not prescribing quetiapine for sleep (he/she was already on nine psych meds, including an antipsychotic, two antidepressants, anticonvulsant, benzo, and others, not to mention half a dozen supplements). So I just had to ask this question today.
