That's a tough choice to be making on your own! This is something that needs to be discussed with your physician.
Meanwhile, do some research online! Look at the reported side efects, read about other people's experiences. You seemed to do well on the Paxil, but obviously it left you feeling a lack of some sort. Perhaps a trial of
Zoloft might be helpful, and then you can compare how each made you feel.
I feel sure that if you bring these concerns to your MD, he/she can discuss this with you and together you can come to the decision that will work best for you.
Good luck... if you wouldn't mind, let me know what you decide and how it works for you!
