Day two on Zoloft

I started taking Zoloft yesterday around 7pm, didn’t really feel anything but this morning I woke up from (what I think Is a night terror, I don’t really know) a dream where I was falling or being launched and that’s all I remember. This was at 8:30 am which is a very unusual time for me to be awake. It felt like I had had way too much caffeine. I decided to start taking it in the morning instead, but until around 5 or 6 pm I was all jittery, anxious, and jaw clenching also wouldn’t stop. Is this all from Zoloft or just a placebo
