Any advice on drying up breast milk?

I’m currently 2 weeks into trying to dry up my breast milk. I was pumping 30 minutes every 3-4 hours, about 5 or 6 times a day. Now I’m down to 20 minutes every 5-6 hours, about 3 times a day. And I feel like I am not drying up…I cannot go cold turkey because unfortunately I am prone to mastitis because I clog very easily! I just need a little advice on this😭🫶🏾
