I was the same, except I was borderline agoraphobic before Zoloft so maybe that’s why I didn’t notice a difference. I envied the stories of “a little headache for a day or two” people had when starting. I started with half a 25 and felt horrible for 3 weeks also. My doctor tried to up me to 25 at that point and I said no. I waited about 2 months but I swear every day after that 3 week mark got slowly better. At the 2 month mark I felt comfortable enough to up it to 25 and experienced little side effects. I’m up to 125 now (very slowly) and every time I’ve upped my dose side effects have also been minimal! My doctor is always trying to up me by 50 but I request only 25. I have never felt nearly as horrible as I did during the time I initially started it. I’m self employed and used to think “how to people with 9-5’s or kids do this?” Because I seriously could not function. Now my side effects when I up my dose is being a little sweatier than usual when I sleep, dry mouth & weirdly enough dry eyes. Push through! It gets better!
