Lung,
A point that has to be made, right here.
You have heard a bit about "Accountability", "Accountability Partners", and "Blocking Software", and you will undoubtedly hear a lot more.
Know, up front, that these are "Band Aids." Useful, initially, but never to be considered true answers to this problem.
The heart of the problem is the heart itself. A change of heart and mindset is needed to get over the addiction once and for all. And only Jesus can make our heart pure. Humility to submit to God's will is important. Its a good sign and a good start that the OP has acknowldeged his weakness before God.
