Hi amarafay, I guess you would have to look at the reasons why you have decided to start decreasing your antidepressant. Depending on your diagnosis (major depression, situational depression, ect.) often times when we start on an antidepressant and reach that thearputic level, feel stable and perhaps well enough to deal with our lives and situations without the medication. Depression and like disorders are chemical imbalances in the brain and this is very difficult if not impossible for us to control on our own. I am not saying that there are not some people who can live without antidepressants as there are and they do effectively manage their lives, but for the most part there are many who do need to continue with some sort of medication.
My suggestion to you would be to give your doctor a call and just let them know what is going on. Maybe you needed to taper off of the Effexor slower, or maybe they would recommend another medication at a light dose...I dont know, but do please do keep your doctor informed of how your doing. Letting this go on too long can be dangerous.
