Hi and Welcome,
I also hope that you will try NA or CA. There are wonderful people int those rooms that understand what you are going through, because they have been where you are. It's not easy, but it is well worth it. I used the drug you speak of daily, for many years. I haven't touched it in over 4 months, thanks to NA/AA and SoberRecovery. Keep posting, and check out a meeting.
Sherry
