Switching from Zoloft?

I’ve been on Zoloft for a year at 100mgs. Recently upped to 150mg but am still with extremely high anxiety. I think my body/brain got used to Zoloft? I have my appointment with my prescriber on Thursday and was considering requesting a switch. What has been your experiences with switching? Did you do a direct switch or taper? How do you feel now? How long did it take to feel like it was working?
