I agree with another poster...be careful with Klonopin. Any benzodiazepine can cause or worsen depression over the long haul, but Klonopin is particularly horrible. I remember when I was on 2-3mgs Klonopin per day in my late teens. At a certain point, I'd wake up with anxiety and the worst sort of soul crushing sadness imaginable. So, what'd I do? Reach for my morning Klonopin. Turns out...

...that happens, with any benzodiazepine over the long haul ("inter-dose anxiety"), plus Klonopin will dampen your mood like no other sedative.

1mgs PRN isn't a whole lot. Just sayin' be cautious, if you can. Antidepressants are weird...they often cause mood instability in people who are susceptible, but some doctors will use high dose SSRI drugs for "mood lability." I don't know what that's about. My own limited experience is that high dose SSRIs will flatten anybody out, so I guess that's what's going on.

Have you ever tried a daily anti-epileptic as a mood stabilizer? I think lamictal is popular for people who have had multiple episodes of depression. I take a lowish dose (100mgs) with another anti-epileptic, trileptal. Anti-epileptics can also help anxiety and agitation, at least over the long haul.

Hope you and your prescriber can fine tune things appropriately.
