It likely will go away, when users change from their opiate of choice/use, there is usually a 2 to 4 day break in period with sub before they feel stable. It should level out. What I am saying is tho, your comparatively small habit should most likely be challenged with a week of just feeling rotten, good nutrition and plenty of fluids. Also, Not recommended to all, but an occasional stiff drink could settle some symptoms during the first week, it worked for me. You could be done in a week, then have some blah weeks to follow, but not unbearable, just a little uncomfortable. Getting into sub seems more dangerous than naught. I found my sub withdrawal more difficult than coming off oxymorphone (stronger than oxycodone). Like I said, it seems you are hunting small game with a cannon. try the sub for a few days since those can be the worse. I am not a doctor, but if I was I would say 2mg to 4mg max of the sub per day. Its you and docs choice tho. Hope it works out.
Edit: I have known folks in your situation get by on 1mg to 1.5mg per day of sub, then quit. They literally took crumbs off the subutex pills or 1/8 inch slices of suboxone strips....... less is more with sub....common knowledge of those who tried it.
