@SemAntiKast I take 3 a day of something. It comes in sheets of 10. In boxes of 3 sheets. When I open the box I take one from each sheet. Now all the sheets have multiples of 3. I usually save a sheet with 6 incase we stay overnight somewhere I like to save a sheet with 3 on it so I can take it to a cafe and throw the empty out I'm sure this is normal behaviour
