Slow tapering up

Has anyone here started Zoloft (sertraline) at an ultra-low dose and increased it really slowly because of medication anxiety or being really sensitive to medications?
I’m thinking about trying something like 3 mg for a week, then 6 mg for a week, then 9 mg for a week before continuing to increase slowly.
Has anyone done something similar? Did it make the startup side effects easier to tolerate? Were you eventually able to reach a therapeutic dose, and did it help? I’d really appreciate hearing your experience.
