The Prozac "one dose" deal might be right for if you were off completely of Cymbalta for around a week and were having a really hard time. Check out this post regarding a woman who weaned with Prozac
and Cymbalta, you can private message her and ask her, she answered me back pretty quickly, I am no doctor nor can I say just go out and do this:

You are still on Cymbalta, and did not tolerate the 60 to 30 jump as you said in your first post - I put those dosage options up there to show what doses can be made from what is commercially available without resorting to counting pellets and halving the dosage by the eyeball method. You and your doctor need to decide. Those dosages may or may not be right for you, but do show you that you can drop to either 50 or 40 instead of going straight to 30.
Typically, you stay on a lower dose for a couple of weeks or more (feeling good on the newer dose, not crazy). Note, the key here is feeling stable and healthy for a good period of time before dropping another dose (always with your docs advice).
You felt bad the entire week you dropped down and it sounds like you "modified" your own dose just yesterday. It probably is not unreasonable that you feel a little emotionally screwy, but if you feel you are in danger of any kind, you need to go to a walk-in clinic or emergency room.
As soon as possible, you should get to your doctor to help you get on a safe track with this.
As for the answer as to how long does it take people to get off and feel normal again - everybody has a really different (but similar) experience. Some people feel better in a few days, a few weeks. Check out some of the posts, many people ON THEIR OWN reported feeling better this past week and it took them around a month.
And, lastly, some people do come off of this and have no problems at all!! They just don't post here because, why would they look for a support forum if they were feeling fine and dandy?
You might be lucky if you can get your doctor to work with you to find a gentle quick withdrawal program. Be careful and safe and please let us all know how you are doing, feeling, what your doc said, etc.
