Hey @Former-Member (did you notice fancy_pants' display pic by the way? super worth you reading!)
I only have experience taking non-standard doses of antipsychotics for sedation (I hope this is still within forum guidelines - sorry if not, I'm trying to be careful!). No increase in appetite with them but not sure if it's because they were prescribed perhaps for use in a different way than usual (if there is a usual way, but hopefully you know what I mean). In saying that, the AD I am on is apparently notorious for weight gain, increased appetite etc and is currently having no effect of that kind on me, if anything it is decreasing them.
I guess that shows how individuals respond differently to meds of all kinds.
