Well, my shakes are also 3 a day:
1 morning with breakfast.
1 after lunch.
1 after workout.
The creatine at the moment is at a"loading stage" of 4x a day, so im popping a spoonfull in each shake and one in a glass of water before bed... perfect.
(After a week, creatine is used only once a day before working out, so no longer such an issue)
