Hi Bfree,
Well, I would suggest you make a plan for when you return home. You have 6 more days with your mom, then what are you going to do? For me, I had to change my patterns and routines, sometimes a lot. During the times when I would have been drinking I had to force myself to do something else, something specific. You can walk the dog, exercise, watch a good movie, have a bubble bath, make cookies - do something to take your mind off the coke, even for just a short while. It works!
Coming online to SR is always good for me too. There is always something inspirational to read.
Love, Anna
