I so wish I had done what you are doing 6 years ago. I lost sooooo much by letting my pill addiction explode. I was taking the same amount you were - 8 10mg Vicodin/day and no matter what I did my addiction just kept getting worse. I was 1 cm from losing everything. THANK GOD you made your decision. I highly recommend going to a few NA meetings. The support you will find is amazing and you just might need it in upcoming days and months.
Your children are truly blessed. As a recovering addict and a teacher, I can't tell you how much addiction hurts our children. Two children poured their hearts out to me last week about their addicted parents fighting. STAY STRONG and do not give in. You have two beautiful people + wife (I am sure she is wonderful too)
that need you. You are in my thoughts and prayers.
Love
