I take Prozac right now but my doctor switched me to Zoloft (sertraline) I'm scared to switch to Zoloft (sertraline) will it give me energy like Prozac?

Don't be afraid. Zoloft (sertraline) is not likely to give you as much energy as prozac, but there is unlikely any need to be afraid. Zoloft (sertraline) has cleaner metabolism than prozac, however, and is less likely to cause syncope and palpitations than prozac.
