Hey Tetra
Just my two cents but I would have a chat with a D&A specialist about rehab. Its just that you've had 8 months of sobriety which doesn't seem to fit the typical profile of a rehab patient. When I had my last meltdown, I also considered rehab. All my family and friends thought it was a great idea. Even my psychiatrist thought it was worthwhile. Then I sat down with the Specialist who ran the rehab. He recommended that I NOT do rehab as he felt it had no value. The reason being that I was not, in his professional opinion, dependent upon alcohol. Certainly, I was having these binges but I was capable of abstaining for periods of time within a normal environment. He recommended sessions with a clinical psychologist specializing in mindfulness practice and CBT.
I did that along with a swag of other tools such as AA and finally managed to stay stopped (fingers crossed).
In summary, I agree with the other posters in that you need to decide for your own benefit, secondly, to seek professional advice and finally, to ensure that all other avenues have been explored as well. I have been attending a weekly AA meeting with rehab patients for over a year and have an idea what a rehab patient profile looks like.
