All adverse events will be recorded and reported. Subjects will be specifically asked about adverse events. All events will be recorded by the investigator in an Adverse Event form and each event will be recorded separately. The research team do not anticipate any adverse AEs. However, if there is an AE the research team will report the incident to NHS Ayrshire and Arran Health Board's R&D Office within 24 hours and this will be followed up as per the R&D policies and procedures.
