Mike! I feel the same way! I truly wish I had a great answer for you but...I don't. Perhaps the Paxil needs to be changed?? I just started on Fetzima and after two weeks I'm feeling just as you described. Stuck between depressed and normal. I almost wish I was manic so I could get up and do SOMETHING.
I hope you find the end of your slump soon. Perhaps another talk with the doc?
