This is a common occurrence due to the fact that each scoop of powder can slightly vary in size. If you have shake mix or a supplement powder remaining whenever you are supposed to be finished with a supplement, simply continue taking it the same way that you have been until it runs out.
If you have been given a new supplement shake mix to start, you can combine the powders to make one shake until you run out of the initial mix.
If you have leftover KetonX, you will need to continue to do this one alone 15-30 minutes before any breakfast, including a detox shake. It may be helpful to have your single shake in the place of lunch or dinner to minimize the amount of liquid you have during breakfast.
