Thank you for your question and welcome to ADHDCentral.com
I am not a medical professional and would not be able to give you medical advice.
Although I am not familiar with Suboxone, I did look up the side effects and saw that the list included constipation and diarrhea. In addition, side effects of Adderall can be abdominal pain and diarrhea.
It would be impossible to say, however, that what you are experiencing is a side effect of either medication or a combination. I would certainly suggest contacting your doctor as it sounds like this is interfering with your ability to function. Your doctor would be able to determine if you should adjust your dosage or try a different medication.
