Can you talk to your pdoc about this? You may need a change, or an upped dose, or more doses during the day.
Do you have any physical health problems? Such as Crohn's or anything that makes it hard for your body to absorb things before ridding it out of the system?
Is there any common things (Situations, meds, and such) that happen or don't happen on the day that this happens? do you get nauseated or have a stomach bug?
