I hear ya, I'm not going to beat myself up over it. The most important at this point is staying sober.
That said, I would really like to stop and give it a fair chance - if only for the money they cost me!
And yeah, we're not all the same when it comes to addictions. For me, for example, marijuana never worked. It's legal here (sort of, with restrictions), but I don't like the buzz, and it did nothing for me when it came to pain relief. I tried several times, with "good stuff", and it just didn't work/feel right.
Anyway, baby steps...
