A portable infusion pump can communicate with continuous glucose monitor (CGM) to receive continuous feedback relating to a user's blood glucose level during insulin or other medicament therapy and can automatically deliver insulin to a user when the CGM data indicates a need for additional insulin. Because patient behavior can interfere with the accuracy and efficacy of such closed loop or semi-closed loop therapy, a system can employ various mechanisms for manual temporary suspension of closed-loop therapy when a patient is aware that current or future behavior may inhibit therapy.
