I recently started and was wondering the same. I know how it is suggested to be taken, but MUST you break them up? Or can I take all 8 at once, preferably before bed time? Or second best option (maybe, for me) is to take 4 once home from work (5pm) with light dinner, and rest before bed?

I'm still trying to figure out how to make it work with my full-time work load and many volunteer hours....away from a rest room. Thanks!
