Have I gone a bit OTT???

I finally have an appointment with my GP to discuss Harry's reflux on Monday (final staw was him refusing to prescribe gaviscon on repeat dispense and said I have to come to the surgery every time I want more - one prescription lasts us 12 days!!!).  A number of appointments have been cancelled previously due to GP cancelling or me having to cancel because he is so sick, the thought of putting him in his car seat and trying to drive alone while he vomits was too much to cope with!

So, being fed up with my GP not taking me seriously, I have prepared a 3 page word document to give him which sets out all of my reasoning as to why he has cmpi.  Harry thrives and does not have diahorrea or extreme eczema so GP refuses to listen!

The document includes the following:

quotes from medical journal articles which explain the links between GER and CMPI and that the majority of cases present no additional symptoms other than GER (this article actually says it is the exception to show other symptoms in a child under 1 year of age).

A 24 hour timeline which notes every time he is sick, how bad it is (on a grade of 1-5), what he was doing at the time). By the way he was sick 42 times that day!!!

A list of the weaning foods he can and can't have.

A bit of history of steps introduced and effects.

Is this all too much?  Is he even going to read it?  I just am at my wits end trying to get this man to listen to me.  If I ask for a referral to a gastro paed am I right in thinking that he can't refuse?
