Requesting ongoing treatment being a side-effect of the treatment is a problem. Especially as we know of drugs developed for medical use which have this effect (e.g. heroin) to some extent.

The whole problem of two states, in both of them I want to stay in the state I'm in, is a nasty one. I have no idea how to solve this, but I wonder how real world it is - have you ever encountered someone who's been in that situation (or are they all locked away in metal institutions which is why we've never met them)?
