sorry raider, I think I finally get what you've done.

Assuming you're talking about the OCR form, the instructions IMO are only asking for your past 3 appointments, not your past 2 years worth. If your 3 most recent appointments are to a chiropractor, then I'd probably use the additional space. So long as you have a GP or specialist listed in the past 12 months, I'd stop as early as you list it. I wouldn't add an additional sheet if at all possible.
