Cymbalta, like other anti-depressants and most opioid pain killers (though not generally Tramadol) can be addictive and generally loses potency over time (note that NSAIDs like aspirin are not addictive).
It is very important to distinguish between dependance and addiction.
Dependence means the patient cannot attain the same quality of life without or on a reduced dose of the drug, this is fine. In fact, it's good: it means the dose is appropriate and the medication is working! Addiction is when the body develops a physiological and psychological [i]need[/i] for the drug independent of any medicinal value.
On to the good news
Cymbalta is a very fancy drug that acts on two neurotransmitters in the brain, it generally boosts mood, improves sleep and depresses the nervous system (lessening pain in patients with hyperactive nerves like in Fibro).
I love it
