Hi,
I was on Cymbalta for about 3 years and it worked okay than when I got really stressed, it pooped out...but it did fine for me. I don't recall side effects or how long it took to start in again. I was on Lexapro also before my family practice doc swittched me. Before that I was on Zoloft. Now I'm on Pexeva (basiclly Paxil) and it is working great.
BUT, Just Tuesday I learned something about Cymbalta you may want to consider and ask your doctor about. I was just diagnosed with Chronic Kidney Disease (CKD or chronic renal failure). I don't know how old you are, but I'm most likely older than you so it may not be an issue.
I did notice in your profile that you suffer from anorxia. Cymbalta is clearned out of the body with your kidneys, where all the other antidepressants , they are cleared out with the liver, which is good for your kidneys. My pdoc just made me aware of that at my medication check up on Tuesday when I told him I had recently been diagnosised with CKD.
So, I believe with anorxia, you are more likely to do damage to your organs. Please check this out with the doctor who manages your meds. If you have had any issues with any organ damage, you need to make them aware
Keep in touch, and let us know how you are doing with your new medication changes.
