Not a good idea, but it's your liver. If you're dedicated enough to work out, and juice, why chance it with etoh? You'll be fine, but it's just the whole idea, and chronic alcohol abuse while on, will fuck up your liver. Willpower.
If you mean 1-2 beers then it's not the greatest idea but probably won't do you any harm. If you intend to go out and get plastered while on cycle I'd reevaulate your priorities. Stay clean and drink all you want.
