Had the exact problem so I know what he is dealing with, the suspension should have been his wake up call.
It sucks, sucks bad but if you want to stop there are ways to get help and get well, if you really want to.
I wish he would have gotten help during his time off. Hope he does now.
That being siad he is one of my least favorite fighters but I wish on no man what he is in for because it is hell.
