Hi and welcome!
Is your primary purpose to come off the med completely, or transfer to something else?
Bead-counting to zero--
If you plan to come off completely, then yes get feeling stable at 30 mg and then bead-count from there. It might take a week or two to feel like you're ready to start counting beads. Perhaps consider setting your bead-counting timeline at about 10 weeks and step down 3 mg per week (3 mg the first week; 6 mg the second week; 9 mg the third week etc). Count the beads in a capsule and figure out how many beads equals 3 mg. Get some empty gel caps from the pharmacy or health-food store. Adjust the timeline to keep the symptoms manageable.
Cross-tapering--
Your exposure to Cymbalta (duloxetine SNRI) would be considered low at just under a year, but nevertheless, some withdrawal symptoms are to be expected even when you transfer to another drug like Prozac (fluoxetine) or Lexapro (escitalopram)-- both SSRIs. As the new drug comes on-stream you will begin to stabilize.
It's prudent to taper off the Cymbalta and taper on the Lexapro; it takes 4-6 weeks to fully upload these drugs, so consider taking 4-6 weeks to make the switch, weaning one up and the other down. Talk to the doc about this. I don't know what dosage would be equivalent to 30 mg of Cymbalta-- I think that would be a try-it-and-see thing.
Prozac vs Lexapro? Here's a website that compares the two: http://www.healthlin...xapro#Overview1
One of the major concerns taking two of these kinds of drugs is serotonin toxicity (also called serotonin syndrome). Read about that here: http://www.mayoclini...on/con-20028946
Another consideration is the interaction this new drug may have with other meds you are taking. You can check drug interactions here: http://www.drugs.com...teractions.html
This transfer is fairly common and I hope it goes well for you. Give it some time to work. If you plan to completely wean off the SSRI thereafter, consider doing that over 8-10 weeks also.
If you are having anxiety, you might consider having a benzodiazepine on the shelf for AS-NEEDED. Non-addictive alternatives to benzos are hydroxyzine and clonidine. Again, talk to the doc and keep him or her in the loop.
There are many smart and compassionate folks that will add to what I've said and correct any errors I've made. You've found a great place here-- we all work together.
Take care.
