Going cold turkey with adderall

I've been taking kratom for nearly a year now and my dosage has been getting bad. I take capsules, and I'm at the point where I take 15 in the morning, and 8 in the evening. I was put on adderall back in October and now I'm at 30 mg XR with a 10 mg IR booster.

At first I thought kratom would compliment adderall but I'm starting to think it's dulling the effects. I was on adderall before years ago, and I was on a 20 mg XR dose that worked wonders and I didn't feel the need to have a higher dose.

I wanna cold turkey kratom, or at the very least taper at a very fast rate.

How would yall go about it?
