I have taken Celexa, an SSRI before, and in fact am currently on it since mid-July. Fortunately I do not work with some of the more common side effects of sleep issues and weight gain, for which I am very grateful! As we often say, everyone is different, and the ways we react/respond to medications can be so individual, because we are each an individual! In my experience, taking Celexa does not exacerbate my SAD [social anxiety disorder] or GAD [generalized anxiety disorder] symptoms. And yes, there is formal diagnosis.
Would you tell us about what you have experienced, and tried, that has been successful in achieving what you want to do? I am always interested to know what paths people meander while reaching for assistance.
