Hi Nabley,
I doubt you will get a CGM if your CCG is as anal as mine (Cornwall) I was told that there were plenty of type 1's who took steroids thus I was no different than any other type 1 and as an added bonus I was told that if they gave me one then it wasn't fair on anyone else as no one in the CCG had a CGM.
Your first step is to get a pump as this makes life so much easier, I found using HC only for Addison's was not working for me so I use a combination of Prednisolone and HC.
Also look around for private funding for your CGM, this is what I did. Dexcom is the best CGM to have so if you can get a pump then go for the Animas Vibe this will save you money as the pump has a built in receiver for the Dex.
Oops just reread your post you already have a pump
