background info:  Used opiates for 5 years.  At my peak was doing between 10-15 30 mg roxi a day.  Been on subutek for about a year.  Bought it on the street for about 9 months then started seeing a doctor.  I was doing between 2-4 mg a day when i bought it on the street and now im doing about 8m a day give or take.  I guess im what you would call a functioning addict.  I have a good job and am very responsible for the most part.  I recently started taking adderall.  At first it was just to get me through long drives, i visit my son every week on my days off who lives 4 hours away.  I fall asleep driving all the time and in general I have a major lack of energy.  The adderrall really helps.  Im also a worrier.  I over analyze every thing i do.  Im always worried about dying from drug use, my son is my world and would never want him to have to live with that. My question is... Do i need to worry about mixing these to drugs? Ive been taking about 30 mg of adderrall along with the 8 or so mg of subutek a day.  Ive done research but it seems like there is a lot of conflicting views.  Im hoping someone can tell me i have nothing to worry about because im accomplishing more than i ever have since i started mixing the two.  Im more productive and driven.  ty in advance for your replies
