Zoloft/Sertraline

Has anyone taken this? I’m on a low dose, 25mg, of it and I just began taking it a couple days ago. I noticed from the moment I took it the first day, it has made me insanely tired and sometimes nauseous too. Does this go away? I thought the whole point of antidepressants was to enhance your mood, not drag it down more and make you feel like a zombie... 🤷🏼‍♀️
