Welcome @Badlands,
Since you are reading Anders Sørensen's "Crossing Zero" at the moment, you are setting yourself up for a way better process. I'm not sure how much of the withdrawal can be completely avoided, but having knowledge makes it less scary and way safer.
Here is something for you to add to your to-be-read list, if you want. Two guides from this site that you might find helpful. Everything here is basically echoing Anders' hyperbolic tapering approach, so it won't fight or contradict with what you are reading (not adding to the confusion).

And well, speaking with fellow taperers really does help too, so make use of this community if you like. Everybody loves to help here if they can. I hope your ride becomes less bumpy from here on out!
