Is 100mg zoloft a lot?

I saw a therapist for ppd and anxiety who put me on 50 mg Zoloft. I would say I'm more anxious than depressed. A few days later after no change and increased anxiety he told me to increase the dose to 100mg which I have been on for a week. He said it's still a 'low dose' but the past couple days I've had night sweats, dry mouth, diarrhea and increased anxiety which from what I read online are all symptoms that the medicine is too strong.

I called but am still waiting to hear back. Am wondering if this medicine is making me feel worse and is too strong of a dose.
