We all struggle with BG management at times, it's just the way of it. The Libre is an excellent and fairly affordable tool to assist with managing your diabetes. You'll find TONNES of threads on here regarding it. I can say first hand that it helped me a lot with sorting out my overnight BG and also gave me an in depth understanding of how various foods impacted my post-prandial levels.
This following book is brilliant for us T1's (and insulin dependant T2's) - I can guarantee that if you were to read it, you'd learn so much more than you already know - even after 11 years. It's the best book I've read to date regarding diabetes management, and I never wrote it by the way
