Switching from Zoloft to Prozac

I have taken Zoloft for 4 years and feel that it has stopped working for me, I can’t stop binge eating, I’m lethargic, anxious, generally apathetic , and my libido is non existent.

I have asked my doctor about making the switch to Prozac and I will be starting soon. Has anyone on here switched from Zoloft to prozac? What were the side effects? When did you notice the Prozac was working?

Thank in advance to anyone who shares.
