"since when did a patient decide exactley how much of their medication they need."

Adults with type 1 diabetes (like me) typically manage their condition themselves. I measure my blood glucose, estimate the carbs that I'm eating and the exercise that I'm taking and decide how much insulin I need to inject. I meet with a diabetes consultant or specialist nurse every six months to discuss how this self-management is going.

"At no point should a user be able to modify this out side some pre set parameters without a medical proffesionals say so."

I'm afraid you're simply wrong. Not just for diabetes but for many other long-term conditions, so-called "expert patient" schemes where the individual is given day-to-day control are quite commonplace. The days when such conditions were micro-managed by a medical professional are (happily) long since passed.
