First, thanks everyone for the nice wishes

... I'm sitting here in a haze right now, having had another infusion this morning. For the most part I try to stay offline after my sessions, but I can't read well right now (blurry vision) so I thought I'd do a quick BL scan.
I'm planning to write at length about my experience with ketamine therapy when I finish the initial course of treatments (just one more to go). But I wanted to reiterate TPD's point...it's definitely not a panacea. At best, it's another piece of the complicated puzzle of how we treat depression.
I did want to reply to what twang asked about. As just-another-guy-with-an-opinion, it's my guess that antidepressants are overprescribed in contemporary America. But that's really just a guess. What I also think is that we do have an epidemic of deeply unhappy people in this country. Some unhappy people are gentically predisposed to depression. Others suffered trauma during crucial developmental stages of growth. Still others live with chronic stress, dissatisfaction with their lives, and ennui. Any of these scenarios can lead to a persistent problem in mood and outlook. Of course, not everyone with these problems becomes depressed, but some do.
For those people, antidepressants can be a real godsend. I resisted going on them for many years. I had my first suicide attempt at 9 years old but didn't start medication until I was in my 20s. When I did, it was life-changing. For whatever reasons, a cloud was lifted from me. I was able to go to graduate school and get married (two of the best things that ever happened to me). Antidepressants IN CONJUNCTION WITH SOME REALLY GOOD THERAPY not only saved my life, but gave me my life...allowing me to reach potential that I simply never would have reached without that help.
Now in my case, at some point, the antidepressants stopped working as well as they did before. Maybe this is something that happens if you stay on them long enough (I'm in my mid-40s now), or maybe it's idiosyncratic to my case.
My overall feeling about the large number of antidpressant Rx's in this country is that it's not ideal but it's not very bad either. All evidence that I'm familiar with suggests that giving antidepressants (especially SSRIs) to someone who might not really need them doesn't incur a high cost. The pills are cheap and their effects in that case are mild (and if they aren't mild, the person is likely to stop the medication). But telling someone they aren't depressed enough to receive medication can have truly disasterous results. So personally, I'm a believer in prescribing SSRIs with a low bar.
The only caveat is that I also believe *strongly* that by far the best results come from combining meds with talk therapy...good talk therapy. And the bummer is that good therapy is expensive and hard to find. That's a real shame.
OK, I sense that I'm rambling now. Time to go back to holding an audience with the dead crow god at the bottom of the universe.
