This should do I think the kpins are overkill for this tbph.
Dont psyche yerself up about this.
It would be best (in my opinion and experience) to wait until WDs are getting bad then start dosing kratom as needed.
Are ya already on the benzo (kpin)? Or just at hand. Is it pharmacutical?
I would not suggest taking any kratom until the opioid use has stopped and WDs set in. Ya can thank me later.

Drink lots of water before, during and after kratom dosing. Water anyway....
Eat as healthy as possible. I know eating and WDs do not mix but once ya get on the kratom eat.
Get some of those boost/ensure trype drinks. Go for the ones with less sugar more protien (the kind for diabetics); I like the chocolate ones. They help in my experience when ya cannot stomach anything and perish the though of eating.
Be well
