Well I am BPD and also BP. I do not recall a single doctor, of many that have suggested lithium as a choice for my mood swings. That's my experience and I go with that and also that Lithium, once again potentially can be dangerous if not kept in check, I'm guessing that it's not a "first choice" Again this is my take, not DeFacto information.

While you're welcome to post in any forum of course, I'm curious as to what motivates you to post information that sounds almost "authoritative" on BPD when you're neither BPD or a doctor/therapist?

Not trying to troll here, just curious. Do you know someone that is bpd, or something?
