How can increase my alcohol intake? Is there medication that can help with this?

I am now at the stage where I regularly wake up vomitting in bed after a quite evening of boozing. I am a solitary booze artist, weaving my alcoholic works in private, smoking, and generally hoping that most of everything will disappear from my mental horizon. I need alcohol to augment these meditations but I find the going is getting rough on my liver, which puts the pukes on me after about 40 ounces of the hard stuff (I seem to have no problem drinking five to six bottles of wine or cider). I now sleep with a garbage bag wreathed around my head so I no longer wake up soaked in a revolting porridge of steaming barf. But it would be nice to get back to boozing more and I remember reading about some British actor who said that in his 40's he took special drugs to help him continue boozing. Anyone know what these are, provided they are legal of course?
