I had this for over 20y type 1 been a few ups and downs excuse pun. Work three shift pattern,but to be honest my dad was diabetic and sister so had bit of help when needed but try to live my life as normal as possible with learning to know your meals like little an often works for me.big Sunday dinners is going put sugar up high then insulin like mine works 30/70 ie 30min start to drop levels then over next 7 hours slower effect. You have to know your body everyone different also on thyroid tablets. Bloods we're ok last check at doctors so I just eat anything I like
