Very interesting thread.
We just don't always know why relapses happen. When they do, and people share, I really try to pay attention. Anything I can learn, I'll take!
One thing I think I've picked up....and I could be totally wrong, but sometimes people say they 'kinda knew' it was going to happen. If I ever feel that way, I will be on SR so fast....it'll make my head spin!
Like others have said.....concentrate on YOU!
