Maybe you can discuss this with your doctor the next time you meet him/her? Like, going over your symptoms and also stating the meds are not really working. Maybe you can get some changes. I'm not even diagnosed yet so I can't say anything about how that usually works... I don't think the doctors would put you on meds you don't need, because he personally wouldn't make any money from that , it would just go to the whole industry. There's a lot we don't know about psychopharmacology though , and how the medication actually works. For some people it works wonders, others might need some different. It's quite individual. So I guess that is why it is important to discuss this with your doctor! That a different brand / substance might work better for you. If not then you can always change back to what you're taking now.

Btw does your sad episodes correlate with your period? Then you might have PMDD. Worth looking into! Mine totally do....

Anyways, good luck!
