Feature to enable cycling of different dosages of the same medicine (e.g. 150mg on odds days and 75mg on even days whilst weening off of anti-depressants). Would need to be able to correct an erroneous dosage in the progress charts (e.g. if one accidentally took 75mg on a 150mg day) and ability to select whether the cycle should be reset due to such an accident, or carry on regardless (i.e. three 75mg days in a row, one the accidental erroneous dosage)
