Hi Em, how's your cough today? I think Beverlie is probably right, it could be your little air sacs in your lungs having a clear out of the evil nicotine!!! You have done so well to stay off them, you should be so proud of yourself as I know how hard it is to give up (not me personally but my Mum). Anyway, it won't affect your surgery so don't worry too much if you can help it. As for that charming little BLEEP BLEEP BLEEP, well you may be a buxon bird now, but you won't be for much longer will you?!!!
