Feeling down while on cymbalta

Hi Everyone,

I'm new here, feel I've learned a lot in reading these posts...

I was diagnosed with depression about 25 years ago (I'm 51), dealth with it then with therapy.  Things  sort of seemed ok for a long time, but I think I was in denial on and off about my depression, not wanting to admit that I still suffered from it.  Anyway, all these years and MANY health problems later, I finally talked to my doctor and I've been on Cymbalta for the past 3 months, 60mg a day.  It has worked wonders for me, I've felt so much better, and fortunately have had no side effects. 

But here's my question.  For the past few days I've been feeling pretty down again.  Nothing is going on externally in my life, in fact things are pretty good.  But I'm not.  Is it common to still sometimes have ups and downs and feel depressed even when you're on an antidepressant? What are people's experiences with this?

Thanks so much.  Glad to be here.

Thanks, Geebs. I've been out of town for a week and was just able to get to your reply tonight. I'm still having ups and downs. I hate to increase the dose, but I'll talk to my doctor - I have to get in anyway for some other problems (fibromyalgia and IBS issues). I had thought that 60 was the usual dose, so good to know that I can go up if necessary. Thanks so much,
