2 months on Zoloft

I’m almost 60 days in. The first few weeks were rough but after about 4 I started to feel the medicine help everything was good but yesterday I was dizzy all day almost like vertigo I stayed in bed and today I just feel bleh been having diarrhea and feeling anxious. Has anyone else had a setback? Could this mean the medicine isn’t for me or do I keep going? Is it normal to have side effects come back the dizziness was a first for me with Zoloft I’m trying to convince myself something more isn’t wrong. I don’t get why I would get so dizzy all day two months in if I never had that side effect before. This is my first time with this medicine I take setraline 50mg around 830 every night. Just wanted to hear others experiences
