Looney brews - "Blastaway", Diamond White cider and a Castaway is the most potent I can think of. Also, "Snake Bite, any bitter and any cider gets to most people.

As for me, I'm coming out of a very alcholic period of my life and while I still enjoy a couple of pints, I am steering clear of that sort of drink and most of the time I just settle for a couple of cans at home - I hope do manage to keep it under control and don't go back to what I had been doing.
