For 1yr kratom to 6m subs now at 2 to 4mg\day, what's y'all's suggestion?

I want my foot off of the gas pedal of my own taper. Overcoming the [not crazy much] guilt in mismanaging my own taper and gaining control by surrendering to the sublo auto taper, is my goal. I have hopes that once I take my first shot, 100mg within the next 10 days, that I will no longer stress "is the way I'm feeling BECAUSE I'm under dosed on subs while trying to taper?".

I plan to do 3 100s, but the time frame is my main concern. At a low average dose, we'll just call it 4mg for the last 6 months average, the doctor is suggesting MONTHLY 100s, but I read somewhere on here that something like 1st 100 , 3 months later 2nd, 3 to 4 months later the 3rd. How would that line up with y'all's experience? Mentally\emotionally\spiritually I'm free, the "pain" that opiates once covered in my heart has been meticulously been healed by my healing journey and now I'm just left with a physical dependance that's garbo because I can't stand feeling like a zombie a lot of days, especially when my ADHD medication and symptoms come into play and I have a HUGE exam on the 17th.

So what's a fair and reasonable timeline with my timeframe and dose, to getting the 100mg shots? 100mg again a month to 6 weeks later seems like it may be too much?
