Resurgence of Restlessness and Anxious Energy

I’m on day 14 of 50 mg of Zoloft, the first few days I felt restless and anxious all day. Then it kinda went away and I felt pretty relaxed with some anxiety. Now today I’m feeling on edge and restless again. I read that typically symptoms start to die down after 2 to 3 weeks but this resurgence is kind of weird. Just wanted to hear if others experienced this as well.
