Hi Shel,
I remember when I started out on Sub, I was on 8mg, and for the first couple of weeks, I had some nausea and headaches.It did go away after that.My doctor said that it is common for patients who are just starting out- with the body adjusting and all.
Also, please don't rush your recovery.I understand wanting life back to normal, but if you try to get off Sub before you have done some serious work in recovery- you might experience some problems.Your addiction did not happen overnight either, so just give yourself time to heal inside and out.Take care.
