I don't have bipolar, but do have PTSD (complex trauma) and possibly a dissociative disorder.

My treatment consists of once-weekly therapy with a clinical psychologist, which is slowly becoming more trauma-focused (slowly because my triggers are numerous and i dissociate extensively at times), a once-weekly session with a community mental health care manager for support around 'now' stuff (sometimes that includes the fallout from therapy sessions), and monthly appointments with a psychiatrist.

I also take one psych med - Prazosin.

My nightmares and hypervigilance were becoming more overwhelming as therapy progressed, and my care manager had read about Prazosin being used for PTSD and felt it could be helpful. He referred me to a psychiatrist in his team and she agreed with his assessment and with my T's dx of PTSD. (Pdoc is also now assessing me for a separate DD.)

I started on a miniscule dose of Prazosin and was slowly titrated up. Been on 10mg/night for three months or so and it's working well in terms of reducing the nightmares and nighttime hyper-vigilance (and also somewhat with what my team refer to as day-nightmares). Still have times when badly triggered and the nights become terrifying again, but it tends to settle after a few days now, rather than dragging on for weeks.

Haven't been on any other psych meds so can't offer advice or opinion there. I just know that, for me, it's therapy + Prazosin that keeps me functioning (albeit in the loosest sense of the word at times).
