I can't help but wonder if it's not perhaps the combination of meds your on. You say you are going "off" the Xanax, but you don't say how long you were on it or at what dosage. It may be possible that your doctor is weaning you too fast and this will produce many of the symptoms you are experiencing. You also don't say how long you've been taking the Cymbalta. It can take up to four weeks to reach its therapeutic level, and sometimes you have to go through some weird side effects before it reaches that steady state. These are issues you really need to discuss with your doctor. Only he/she can evaluate your reactions to these meds..........and we all react differently. I would ask about the Xanax taper while you were there. None of us can recommend a particular med for you. We can only give you our own individual reactions and opinions. It is your body and only YOU can determine what is right or not and sometimes that takes time and it can also take some trial and error. Being patient with anxiety is difficult. We all want a quick fix and for the most part, there just isn't one. So, have that talk with your doctor, get all your concerns on the table and ask lots of questions. It is your right to be told about every aspect of a medication your doctor is giving you.
Good luck, keep us posted, OK?
Peace
