Like I said, any more is beyond my level of understanding of these things. All I can say for sure is that the GABA system is incredibly important, and kinda delicate.

Read up on delirium tremens, for example: long-term alcoholics, and benzodiazepine and barbiturate addicts need to be really careful in stopping their use of those drugs — they could die if they aren't. Those drugs also affect the GABA system.

Maybe the long-term down-regulation of some aspect of GABA-A metabolism by finasteride's preventing the formation of an agonist for those receptors becomes permanent or semi-permanent after a while? I really don't know.
