I don't even think any stimulants really help writing. You talk to most guys and they say, "Hey. I wrote this." And they're out of their head or they had a few beers or a bottle of whiskey. You wake up the next morning, it's usually pretty crap. But you know Dylan Thomas wrote some great poetry. Brendan Behan. You never know but ultimately I'd say you have to get up early in the morning and you're usually sober when you write your good stuff; it's hard work. So alcohol, keep it for chilling out, fun, and having a good time. Not for work.
