I Read The Answer Above Saying To Start Suboxone After

I read the answer above saying to start suboxone after 24 hours. I also read that I must wait at least 48 hours. I'm confused and scared. The last time I tried to quit oxycodone I only waited 12 hours and ended up in the emergency room. After going thru that I'm now really worried about the time frame needed. In snorting 4 per day. I just want my life back ... Is waiting 24 hours really an accurate and safe tome to start soboxtone.
