I take the generic variety of Cymbalta. I've been on Cymbalta, or it's generic equivalent, for about 2 years. It's not great. But it's helpful enough that stay on it.
The thing I notice, that perhaps relates here, is I still cycle down into depression. But it seems the medication only allows me to dive so deep. Then, at some point, it seems to stop me; & it hauls my useless butt back up!

It's sort-of like a tether. So I still have the depression to deal with. But, at least so far, it has not gotten so bad again that I have made any further suicide attempts.
So, perhaps Zinco, you're having a similar kind of experience. Perhaps your med isn't going to eliminate your depression entirely. But it may prevent you from diving for the bottom. If that is the case, & if you can depend on it to do that, then you can develop coping techniques for the periods of depression you do experience; knowing that the medication will prevent you from sinking too far. It would be great if we could find a med that eliminated our depressions altogether. But, until such a thing comes along, what I've described is not a bad place to be!
