I liked the story told of the relationship between Sam and his family. It was real, powerful, and the reconciliation between them was a nice way to end the piece. A particular scene that caught me was when he was in the hospital talking with his parents. It was sad, a fight, and reminded me of something similar a friend of mine went through. Dislikes, well, I'll nitpick a little, but as somebody else stated, the switching of Point of Views was hard to keep track with. Other than that, it was a very powerful story. Well done!

Aw, that was so sweet! I teared up at the end, I did. I really love how frantically written this is in the beginning, it really helps show how Sam is feeling through his detox. And it, very smoothly, becomes less and less frantic as Sam gets help and becomes a better man for it.
I love the ending and how it ended up being a happy one, with the reuniting of his old family and the soon uniting of his new family. It's a very endearing story. There were only very small things that bugged me.
I feel like the first paragraph is too different than the rest of the story. It's written in stream-of-consciousness narrative form while the rest is in first person. It can throw the reader off guard when switching POVs with out warning. Maybe separating them some how? With a page break or italics or some such, just hint at the difference.
Little, little things~
["not I had better things to do, right?"] did you mean "not Like I had" or "not had I"?
["but how what((was)) I going to let all that go? The smell, the taster((taste)), the feeling inside of my((me))"]
["—the explosive eruption of speed and adrenaline—I would miss that high the most."] I don't think the dashes are needed. These together could be their own sentence.
There are more of these little things, but most of them, I'm sure, can be easily spotted and fixed with another read over or two.
Very nice, major props :)
