Cymbalta is a SNRI, Serotonin and Norepinephrine Reuptake Inhibitors.

Celexa is a SSRI, Selective Serotonin Reuptake Inhibitors.

Difference: SSRIs works on serotonin only, where as SNRIs work on serotonin, norepinephine, and at higher dosages dopamine.

I've been on Cymbalta before, but currently I take Effexor XR, which is another SNRI. I also take Mobic for all of the inflammation and Skelaxin occasionally for muscle spasms.

I find that many doctors won't give you the good pain medication when your on medication for bipolar/add/ocd. I have Degenerative Disc Disease and Fibro, but apparently that's just all in my head. Sometimes I feel like telling the doctor to take a knife and stab himself in the lower back, then try to function for a week of sitting 8hrs a day at a desk.
