I experienced the most significant
side effects at about the same time period on
zoloft that you are. Some good folks on here, plus my psychiatrist, advised me to wait at least 4-6 weeks, because it takes time for the meds to level out in your system. I'm on day 55 on zoloft and all my side effects are gone. Just my experience, though, yours may be different.
I'd give it a solid 2 more weeks. Keep focusing on good things - what is better vs. what is worse.
