I feel your pain. First, you have to remember that sometimes things happen with T1D that are totally and completely beyond our control. All you can do is try to tease out what is causing this issue and address it as best you can. It sounds (and I may be wrong) that you are experiencing the “dawn phenomenon.” Is it possible that you’re dropping really low sometime in the middle of the night and then rebounding? I don’t know if you’re on the pump or not, but now might be a good time to look into that if you aren’t. The pump really cured me of my dawn phenom issues.
Being a woman with T1D is hard. We have crazy hormones and those hormones can necessitate changes to our regimen on a weekly or even daily basis. For example, I know that the week before I get my period, my BGs go high. I up my TDD by close to 10 units during this period, and even then I’m still high sometimes (and I’m generally fairly insulin sensitive, so this should tell you just how much those dang hormones can affect us!) Then, about a day or two after my period, I am really prone to wicked lows. Sometimes I can go a whole day without hardly bolusing more than a unit for each meal during that time. It’s weird.
Stress too can definitely wreak havoc on BGs! When I get stressed, my BGs go up. The hormones we produce when we’re stressed (those “stress hormones” like epinephrine) make you more insulin resistant. I’ve never found a good way to deal with this, but just understanding the correlation helps me.
Diet obviously plays a huge role in the management of T1D. Another thing that has helped me improve my numbers this past year has been going “lowish” carb. I try to keep my carbs around 100g/day. I have noticed that doing this really helps keep away the big fluctuations. I still fluctuate and still have times when I’m well over 200, but they are definitely less common and easier to deal with when they do happen.
Also, you don’t mention this but I wanted to throw it out there (because you mentioned lack of sleep) - caffeine can cause BGs to go up. If you’re drinking a lot of caffeintated beverages, that might be causing the higher numbers.
Finally, keep in mind that because you were more recently diagnosed, you may be seeing the last of your “honeymoon” period. If you’ve lost the last remnants of your beta cell function, that is going to cause your insulin requirements to go up. Have you talked with your endo about increasing your basal insulin?
Hope this helps and hang in there. Even D veterans go through bad times. Sometimes you have to just let it ride and tweak little things in your life (diet, schedule, doses, etc) to see what the culprit is.
