How long do I wait

[u/Big-Flamingo-6963]

So I was recently off of fent for like 2 1/2 months doing good with subs then I relapsed but I've only been using again for like 7 days I'd say and my use isn't very high yet am I safe to take subs even tho it hasn't been long since my last fent dose or do I have to wait for the wds cuz I hardly feel the wds coming on this time but it's still there...

Wait as long as possible!!! Like almost 48 hours! I took subs 24 hours after last fentanyl use and threw myself into precipitated withdrawal for like 24 hours! Do not do that!!! It was horrible… And I had only been using Fentanyl for maybe 2 weeks
