I haven't tried reducing them as I was anxious this would cause me to go lower, but I will definitely give it a go, I check my BG's 3/5 times per day anyway so I guess I will soon know if anything untoward is happening. It could very well be my body constantly trying to achieve this level - I never really thought about it that way. Thank you, I will definitely try and see what happens. I didn't realise there could be many other factors, I will talk to my specialist and make sure I know exactly what's going on.
Thank you both, you've been so helpful!
