Re: how long does it take to have a BM after taking castor oil?

Ill bet she knows now how long it takes and how long it lasts.

A teaspoon is a small amount that may be noticed the next day or may not be noticed at all as you mentioned.

Three tablespoons is a lot for most and tho it may take a few or more hours to start working, when it does one will be "offline" intermitantly for more than a few hours, and evan longer with some constitutions.
