P.S. When my grandfather wanted to stop his Cymbalta (after being well informed of the Pros/Cons), I just sprinkled a tiny bit of the capsule into the trash and closed the capsule back up. Each week I sprinkled a little more into the trash. You MUST NOT swallow the tiny beads without the protective capsule coating !!!
