Treefa nailed it.
Suboxone is made for people with serious Opiate addictions.
Like myself.. if you get 'high' on Subs, then you're totally fucked. Suboxone is not for you.
When I take a 4mg dose of subs, I'm still doepsick... I'm Rx'd 16mg of Subutex daily.. and that hold me for 24 hours.
But if I IV or snort my subs, I do get pretty high..
bottom line is, a 2-3 week run of opiate use, is no where near ready to take Suboxone.. you need to be addicted to opiates for a bare minimum of a year, taking STRONG opiates such as Heroin or Oxy to even consider Suboxone.
While I agree with some of the above-posted sentiments, I feel like we're glossing over an important factor in this scenario, namely, the phenomenon known as the Kindling Effect. What is this? Well, essentially, it's the ability for a previously dependent individual to reinstate their previous dependence at a disproportionately fast rate. Whereas, maybe when you first started using Opioids, it took months of use to develop a habit, now, you can develop a severe habit in less than a week. It's not at all uncommon for an Opioid addict with a period of abstinence to develop a dependency and full withdrawal syndrome after only a few days of usage.
The phenomenon has been more closely studied in relation to Alcoholism, but it seems to apply to other classes of drugs. I can speak from experience that it's real. It takes me 3-5 days of consistent use to develop a dependence/withdrawal syndrome. So, for this reason, it's not an insane notion to think that OP might require some Buprenorphine to medicate his sypmtoms.
We need to be really careful before telling people in absolute terms that they are or are not "right for Suboxone". The OP stated pretty clearly that he is an Opioid addict and that this was not his first fooray into these usage patterns. He's also not trying to imply that he requires a Buprenorphine maintenance protocol to deal with his relapse. It seems like he's just intending to use it in the event that his withdrawal makes him unable to function completely.
At any rate, I don't see a need to acquire any more Buprenorphine. 4mg should be more than enough for your situation. To be safe, I would wait the full 24 hours before ingesting any. If we're talking about Poppy Tea, which is typically longer-lasting, you might do well to allow yourself a full 36 hours of abstinence. It's always better to be safe rather than sorry regarding Buprenorphine. Dealing with a few more hours of mild discomfort is preferable to dealing with precipitated withdrawal.
Also, where are you deriving these numbers/variables from? A bare minimum of one-year addiction? Must be addicted to Oxy or Heroin? I just feel like you guys might need to rein it in a little bit regarding the advice. Everyone experiences addiction differently and their progression will in turn follow a different path. To tell someone that they can't take Buprenorphine unless they take Opioids "...3x - 4x per day for at least a year" is arbitrary and a little bit irresponsible.
This is all irrelevant though, as OP stated initially that this
was not his only prior experience with Opioids. He's an addict who has relapsed and given what we know about the Kindling Effect, it's totally within reason to assume that he/she might experience some withdrawal.
As far as dosage goes though OP, you should definitely be good at 1mg Buprenorphine per day, but I would go with half of that to start and see how you feel. Buprenorphine is a pretty interesting drug and as dosage increases, the more desirable, full-agonist qualities of the medication begin experiencing more competition with the antagonist/partial agonist qualities of the medication. For this reason, there's dual benefit in keeping your dosage as low as possible.
