Quit 9 mths ago ,still crave for one, but at least i can walk to my peg without breathing like an old man.put on 3 stone but i feel ten times better than i did previously. Best of luck you will need it.
Good luck to you Neil, it will be well worth it if you manage to crack it mate, just got to find something else to do with your hands this week end, hopefully unhooking fish!
