After experiencing some initial success taking Venlafaxine, I have reverted back to some of my old symptoms (especially fatigue) without relief. I let it go on for 3 weeks, until I have finally relented and called the doc to see if she will increase my dose to the more normally scripted 150 mg. to see if that is any better. I suspect that my initial excitement was a little bit actual success and a lot positive energy and hope. The fatigue, especially has crashed back in, re-affirming that something more is going on. Only it may not be related to my anxiety.
