I was sleeping and I woke up In a cold sweat. My clothes were damp and I had chills run through my body. When I woke up , I took off my shirt and I had another episode of my body just sweating out of the blue! It freaked me out and it drove me to a panic attack. I checked my temperature and had no fever. It felt like I had the flu . I need to know if this can be a side of Zoloft or is this something different.
