How would you express "I watched for ten hours straight"?
Another way of expressing this would be "10 hours solidly", but I'm not sure if these are idiomatic, Thanks.
Otra opción es:
"diez horas seguidas..."
Estuve diez horas (insert whatever you were doing) sin parar. = I spent 10 hours straight doing (whatever it was you were doing)
Brilliant, thanks very much.
