Ah to be on a train to London and to a yoga event. Get hooked on yoga. I'm only on Day 16, and still really in shock that I've come this far. At night when I've my typical end-o'day urges, periodically while cooking dinner, I kick off my slippers and do some poses; inverted L's against the wall, down dog, basic stuff, but yoga just does a lot I think to relieve those anxious moments. I too have what I think of as addictive personality, or impulse control problems...always have, whether it was pulling my hair out in my 20's or overeating...overdrinking. You'll have to channel some of it somewhere - hopefully to something that doesn't do the harm of alcohol. Best to you!
