I wonder if anyone has anything on this. In the past this cured my ulcers in my stomach and helps when I get a stomach ache. It's also used clinically for when someone acidentally poisons themselves (overdoses) as it absorbs very well. I understand Cymbalta withdrawal is more of a screwed up chemical problem but who knows. Anything's worth a shot if there's any correlation found that may help.
