Hi CM. Welcome to the site. The every other day thing doesn't work because Cymbalta has a half life of 12 hour. All you are doing is jacking your blood levels up when you take the medicine and then your blood levels drop 75% during those next 48 hours, big withdrawal, then yoou take a pill and jack your levels back up. You keep repeating the withdrawal over and over. Bead counting is the best way to go.
You need to get stable first. Do you think you can stay at 30 mg/day until stable? If so just stay there until you get feeling better.
Bead counting, is where you open the cymbalta capsule each day and remove a few beads, usually 2 or 3. So the first day you remove 3 beads, the next day 6 beads, the next 9 beads etc. This provides for a slow steady withdrawal. If symptoms get to bad you just hold at that dosage for a while until you stabilize. Then start dropping again. Be aware that for most the last few beads give the worse withdrawal. Be prepared to slow down when you get to the very end. Now this is just an example. Some can only remove 1 bead a day and others 7 or 8 beads a day. You will have to play with it a little bit to find what works for you. This doesn't mean you won't have withdrawal but it will be lighter and you will have some control over it.
