Very, very sad news Ron. Breaks my heart. You will remain in my prayers, as will your wife. Having lost most of my immediate family over the years I still know deep down that losing my wife would pretty much dwarf any problem I've ever had to face. And I say that knowing full well that my relationship with her is very estranged at the moment.
I won't say anything superficial, but please believe that you shouldn't beat yourself silly after relapsing, considering the enormity of your struggle. You still have those 15 years mate, they're not gone from this trying time. When you can, and only when you are ready, start remembering your wife and how she would want you to live life with her not there. That bottle is likely the last thing she would want for you. Right now do whatever you feel needs to be done in order to grieve - while keeping in mind the bottle will only exacerbate the pain and delay the grieving you are meant to face.
You have me at your disposal at any time, day or night. PM me for anything.
