Though sex probably has the opposite effect. For example Schrodinger took a vacation with his mistress to work on the wave equation, which he did between lovemaking sessions.
But Erdos was always on drugs so he might not count.
Not always. There was this one month he lost to a bet.
Always minus a month is still always in this kind of context. Otherwise, I would have also meant that Erdös was also on drugs when he was a baby and during his childhood, and I guess it's easy to deduce from context that wasn't the case. I already knew about the one month anecdote but didn't thought it was relevant for my reply.
Yes, it was not relevant. But since we are talking about anecdotes anyway..
