My pdoc keeps adjusting things until I've got the best possible control of my depression. We are still trying new antidepressants. Its a long process but hopefully this one will work out well enough.
I think you should keep on trying for better control if you are feeling like that. Are you still getting manic or hypomanic as well as the depressions or just the depressions? For me abilify controls my manias really well so we just have to keep on trying different antidepressants until we find the right one. It really sucks to change meds cos you have to taper down and then back up again and they don't work straight away so its a bit risky.
