So, last night I used pretty heavily (two Opana 30s from 7:00pm - 4:00am. My last line was at around 4:00am. Now, it has been 16 1/2 hours since my last dose of Opana. I was wondering if I could now start taking suboxone? I'm starting to definitely go into withdrawl but I definitely do not want to precipitate withdraws like I have once before while taking suboxone way too soon. I've been doing Opanas for a couple of weeks straight now. Basically, I want to know how much longer I should wait (it has been 16 hours so far) until I start taking suboxone...I'd like to take it as soon as possible but don't want precipitated withdraw.
