I started Zoloft, a low dose of 25 mg, first day I was on it personally, I was EXTREMELY nauseous after eating in the morning after taking the pill, my stomach was ruined the entire day and I have zero appetite. Also, (TMI) but I also experienced diahrea right after taking this pill, which never happens. As you explained, I, too, I felt like a zombie, my head was in the clouds but not in a good way, lol. I will never take Zoloft again. I also felt while all of this was going on, my anxiety went up, whether it was from the medication or me not feeling well, this med was not for me.
