Anyone on Zoloft and Prozac?

Hi. I've been on Zoloft 100mg for a few months now. Before that I was on 75mg. It has helped me to be less nervous, but otherwise I feel really tired and kind of numb.

Then I did something bad on impulse, what caused the increase to 100mg. But now I met my
psychiatrist in person again and he said he will half my dose of Zoloft (50mg) and also give me 20mg Prozac. But I have to start at 10mg for the first week.

Does anyone have any experience regarding taking both? Will it help me feel better? What are the side effects?
