I think 1 hour to 30 minutes prior to the meal would be ideal.
I would put a call into the vet, have him call you back when he has a minute, rather than go by what you read online.
Ask which would be preferable, at bedtime on an empty stomach? Or in the morning 10 minutes before eating?
Tell the vet the exact times you are planning to give the med, as he might like at least an 8 hour interval between doses.
