Would lowering % help me quit?

Hi. Biggest step I ever took was going down from 5% nic to 2.4%, and then switching to solely zyns and/or gum for a few days at a time. Made the mistake of going back to 5% awhile back and here we are. It’s an immense challenge for me to quit cold, and every time I’ve tried, I can’t get past 72 hours without withdrawals becoming unbearable.

However, I know I can reduce percentage of nic in my vape, and my previous cold turkey attempts were always during the peak of my addiction to 5% pods. They also just came out with (I believe) 1.6% pods for my device as well. My question is this: does lowering the percentage over time make it any more doable to quit completely, or even switching to a substitute? My biggest problem is the withdrawal symptoms, and I’m mostly wondering if taking the steps to lower from 5% to 2.4, then to 1.6, would help when I do decide to quit cold or switch to a substitute. Thank you.
