Hi everyone, thanks so much for your support on this and all my venting yesterday, I was just so upset.
Phoned Mam this morning and Dad didn't drink at all yesterday. He even was slightly considerate once he finally got out of bed. He did tell Mam that I had phoned and that I had hung up on him! (I am surprised that he did, it must have had some effect, it wouldn't be something he would boast about!) My family who are at home completely ignored him yesterday, my sister even hoovered and dusted around him. It must have gotten to him that he wasn't the centre of attention.
He got up this morning and was pleasant to Mam and my sister. Mam says its like Jekyll and Hyde. She is in such better form now that he has been sober for 24hours as she hopes he will keep it that way. He even asked her to come to dinner tonight with him and his employees as a Christmas treat.
I know that things are not right by a long shot but we have to live for the moment and it just about looks like this moment might be OK, so fingers crossed that he stays sober til the far side of Christmas.
Thanks again for all your support and advice, its great to have so many friends to turn to at times like this.
