My PCM transitioned me from Pristiq to Cymbalta in mid-2011. I was on it from July 2011 thru late January or early February 2012. It worked well. I began to wean myself off of Cymbalta in late December 2011. I went WAY too fast. I didn't experience any 'brain zaps' as they are called, but, I was definitely moody.
One side effect of the time frame I used was due to what else Cymbalta can treat - fibromyalgia. Once I went completely off of it, my body ached for weeks - everywhere. This was due to the fact that all I had were capsules and just started spacing out the days that I took them. THIS IS NOT THE CORRECT WAY!!! You can buy empty capsules and divide the contents of the capsules up - which is what most doctors I've talked to since recommend. All of the symptoms (aches, pains, moodieness, etc..) were gone by late May, which is when I started to actually heal...
Again, I am not a doctor, this was just my experience and some info from research I have done. I wish you luck with whichever path you choose.
