Type-2 diabetic patients (N=24) will be used in this study. Potential participants will be given information about the study. If the potential participant is willing, Prof. A Collier and the researchers will send the study information pack and consent form to the participant. The potential participant will also be given oral explanations about the procedures of the study by Prof. A Collier and the researchers. A week later, the clinic will contact the potential participant again to ascertain if they have received the pack or if they have any further question. At that point, the clinic will ask if the potential participant is willing to enter the study and if so, request that they return the consent form. An appointment for visit one will then be made. A schedule of appointment for the whole study will be agreed with the participant and given in writing to the participants. The participants will be asked about how they want to be contacted for reminders. In addition, the participant will be given a contact number to call the researcher if they have any question or queries at any stages. Prof A. Collier and the researchers will also send a letter to the patient's GP explaining detail of study.
