I feel much better after starting zoloft 50mg about 5 days ago. I took Zoloft at one point a few years ago and it made me yawn excessively. I had to step down to 25mg. I am starting to yawn a lot again today. It freaks me out I feel like I can't stop yawning. I really don't want to decrease the dose because I feel really good besides the yawning. Has anyone else had this effect from Zoloft? If so does it pass?
