Hi Barbi,
My boyfriend and I are both on Subutex and did not experience any of those symptoms. The first day we both took it we were both completely different people. I haven't had any cravings, I sleep better then I have in years, and my mood has done a 180.
I wonder if your dose is too high and that is why you are experiencing the head aches, nausea and lack of sleep. You should keep a journal of everything that you are feeling and experiencing and bring it to your doctor to evaluate. Communication is a key factor in reaching the correct dosage.
I would also look into support options such as counseling, meetings and clean friends. I find that keeping a strong support network, planning activities to do, and writing in my journal and here at SR help me to reflect on my feelings and grow as a person helps me a lot.
I wish you the best,
