Off of Paxil, now starting Zoloft

I finally did get off of Paxil and stopped having withdrawal. But my
anxiety and insomnia have returned. This was the reason I had to
start Paxil in the first place. I am now on day 3 of Zoloft. I am
having dry mouth, nausea, and dizziness. I was wondering if anyone
else tried Zoloft. Paxil worked for me, but I didn't want to get
pregnant on it. Zoloft is suppose to better. Did anyone else have
side effects and did they get better? Thanks
