Thanks man, I'll keep this in mind!
I have waited like 18 hours before in the past and been fine but I'm just so terrified of precipitated withdrawals

Being so scared if P/WD I want to get to 24 hours at least but twice I've made it to 18-ish hours and failed but given how bad my withdrawals were I imagine I'll have been safe.... I should have just gone for it
To deal with the withdrawals I have Pregabalin, Loperamide and DXM. Last times I failed I only used Pregabs so I imagine my next attempt will be easier if I use loperamide/DXM etc.
I've just ordered some Kratom that's good for opiate withdrawals and trying to confirm whether it can or can't cause precipitated withdrawals like I've said - but given the fact you've done it and been fine I guess I can give it a go. What strain did you use? How soon did you take Kratom before the bupe?
I also bought myself some passionflower pills as passionflower is meant to be good for opiate withdrawals, or so I've heard anyway... Guess I'll find out
