This survey captures a full day's worth of AHC episode(s). It is ideally completed at the end of each day. However, if no episodes occur that day, enter 0 as the number of episodes, and please complete the last page of the survey. When you receive this link, please complete a minimum of 4-6 weeks of daily logs for this study. If you prefer, you can start the survey early in the day and save and return to complete it at the end of the day. If you have any questions please email Helen Chen ( or Abbie Burney (
