Can I say that a musician went dry, meaning that, after some time, he stopped writing hits or lost the inspiration? How else could I say that?
If you changed the context a bit you could use 'dry up', but it's usually things that dry up (and husbands perhaps, on Christmas day ). For example, a river can 'dry up' (or 'run dry').
(A related - but irrelevant - bit of vocabulary refers only to actors. When they forget their lines they are said to 'dry': He was fine in rehearsals, but in front of a paying audience he just dried. Maybe this is a bit of actors' jargon from my mis-spent youth.)
And here I was thinking it had something to do with giving up alcohol!
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
