I guess what I was trying to say, and I guess this is for Marle, having those two years is wonderful. But, do subs teach us the skills we need to maintain sobriety when we're all done with them? I've seen a lot of people on these boards that are on them, all is fine, then Bam! when they're done they start using again, and I think, hmm the subs just prolonged the inevitable.
As a tool, they are fine, but I believe something else concurrently and afterwards is key to success.
