It can take up to six weeks for Zoloft to even get in your system. Have patience and I hope it works for you.
I have never taken the test to find out which antidepressant works best for me but after trying others I always found my way back to Zoloft.
You might want to pair it with Wellbutrin. It is very complementary with Zoloft. So much so they call it Welloft.
Good luck on your journey.
