manicbeara013,
Wow, you sure had a terrible reaction to the serotonin inhibitors -- I've never heard that they could actually cause fatigue. In my case, I just started the Effexor in January (was off the ADs for about a month)... and it took care of my panic attacks that I was getting since September. The AD's don't tend to make me exhausted.

Oddly, it's the anti-psychotics that seem to help relieve the fatigue best... just not well enough for me to pursue goals or accomplish anything. My pdoc won't prescribe more than one anti-psychotic at a time and says that there's nothing that can be done about the fatigue. All the physical causes have been checked out -- no problem there. So it remains a mystery that can't be solved, though I will inquire about Ritalin and see what my pdoc says about that.

Thanks all for your replies. It's helpful at least to hear everyone's thoughtful comments and I don't feel so alone. :-))
