@zoze_j, a few years back my own gp tried to say that I was testing too many times a day and I didn't need to test more than 4 times, despite explaining to him why I needed to test 6-8 times a day he was adamant he was right, so I left it at that and spoke with my Endo at my next appointment which was the following week.
The Endo said that I was right and test strips should not be restricted and said they would write to my gp accordingly, after that my gp never mentioned it again, so if stuck get your hospital team to back you up. Good luck.
