I wouldn't go as far as previous poster that all will be fine once he is 'dried out' but it will give the doctors a better view on what is caused by the drinking and the underlying symptons.
If that is not an option, make sure he gets enough Thiamine (Vitamine B1). Alcohol makes it hard for any B vitamines to get absorbed into the system and Thiamine is essential for nerves. These are pills you can get everywhere.
Normally we get all sorts a vitamin B from food, brown rice, whole grain foods etc. Alcoholics don't absorb those nutrients and since they get a lot of their daily calories from alcohol, they don't eat as well as they should, further limiting their vit B intake.
There's a wikipedia page: http://en.wikipedia.org/wiki/Korsakoff's_syndrome where under causes "inflammation of the stomach lining" (which is the cause for ulcers) is mention as one of the contributing factors.
I'm not a doctor, please let's be totally clear about that and I don't want to sound as if Thiamine is the end to all your Dads problems, but if checking him into rehab isn't an option, imho you should give him these pills. Here in Holland doctors prescribe 25 mg of Thiamine three times a day.
I know those are mega doses compared to the recommended daily dosage, but since it is water soluble it doesn't build up in the body like vitamines A, D, E or K. And it would need to be a big dose to get into the body of someone with an alcohol problem.
I myself have been struggling with alcohol dependency problems for quite a few years, and in my opinion those B1 pills kept my nerves from deteriorating when I wasn't eating well.
What more can I say? google Thiamine (en.wikipedia.org/wiki/Thiamine) and Thiamine deficiency (www.buzzle.com/articles/thiamine-deficiency-symptoms.html) to learn more about the symptons and causes.
I hope this helps your Dad.
Dear Friend,
Well he surely needs to be in a rehab center,in order to get the alcohol out of his life.
There is nothing more i can add, to this suggestion as well as request.
Once he is out of the influence of alcohol, rest all will be fine.
Please discuss, if you want any specific advice.
Regards
