Eating tuna before bed or drinking a shake like aussie casein or both?

Hello everyone. I am not very experienced with knowing which proteins absorb fastest or slower than others.
I was curious if eating tuna before i go to bed would be sufficient enough to last 6 hours or should i drink a shake with it?

Also, does mayo help slow the absorbtion rate of tuna when added to it?

Thanks

Fatty foods slow down meal digestion, so eating your tuna with mayo should approximate drinking a slow-digesting protein shake (i.e. any protein with added fats or protein mixes containing casein).
