Goodluck, I battled with an addiction to SI too. No one ever takes me seriously when I say it was the hardest addiction to stop. Cigarettes and alcohol were a walk in the park after that! Keep trying, the longer you stop for the less you think about it. Its been a few years since I was doing it regularly and I do have slip ups from time to time but they are much easier to get over now. It does get better hang in there, do it for your best friend if not for yourself.
