"So if you can prove that you need supervision for example, because you are falling over drunk a lot and so at risk of falling into traffic, etc, then the fact that this is because of alcoholism makes no difference to entitlement."
It does now and has done for a while. The DLA form asks you to only state the symptoms not conected to drink or non-prescribed drugs. You can get DLA for the impact that the effects of addiction has on your life ie a transplant, but not because you are an addict, this is a common mis-conception.
Interestingly enough, the majority of cases of cirrhosis of the liver is through paracetamol, including the over use in childhood. As many threads on here show parents refuse to follow the guidelines and dose their children up and teach their children that the use of paracetamol is something not to be worried about.
I also had a friend die of alcoholism, started to ease the pain he was in after an industrial accident. The doctor told me that the result would of been the same, liver faluire, if they had of given him adequete pain relief.
Years ago he would have died, but they pinned him back together, instead of letting him and this is adding to the numbers of people needing transplants, the effect of prescribed medication is often ignored by the general public when making these judgements, which would be a nightmare for an ethics commitee to decide.
