Thanks for the support ladies,i just can't help but feel a bit guilty/ashamed/stupid for still wanting to smoke when I know it's bad for me,especially under these circumstances,i am lucky enough to have a supportive family which I'm extremely grateful for,my partner does nag a little about it(reformed smoker,who had no trouble giving up)but he does understand it's hard for me..will update tomorrow or next day RE surgery to remove necrotic skin..hope everything OK with expander otherwise that will be coming out too, xx
