Yes, I am so unbelievably sensitive to HUMALOG I have given it the nick name 'rocket fuel'. I used to have very similar issues which you are having and this is what worked for me:-
I was sleeping through hypos and contacted a DSN who told me that nocturnal hypos are not good so she advised that I have a milky hot chocolate drink right before bed and omit the 10 pm inj of Levemir. So that was exactly what I did. BG ran high 16 mmol all night so corrected at breakfast time, had ALL injections at my usual breakfast and whoooosh. Blood sugars went beserk, 23 to 25 mmol at about11:00am that morning! I was nearly needing to contact NASA to bring them down and omg never again am I stopping a night time Levemir!! I realised that Levemir was only lasting for about 18 hours a day and I need 2 injections not 1. DSNs were going ballistic with me on the DAFNE course last July for refusing to stop my night time Levemir, due to hypos which they had asked me to do for the same reason, but I stood my ground and I am so glad I did.
So I decided to go back into 2 inj of Levemir ( without speaking to DSNs ) and also because I eat during the day and not at night, I decided that I will have a higher dose of Levemir in the morning and a lower dose at night. I was scanning and testing blood through out the day and recording my bg on the mysugr app. Careful notes are important because diabetes type 1 requires us to juggle many balls in the air without them falling on us and I find making notes about my doses on a whiteboard helped me a lot during this time. Anyway, night time hypos were caused by Levemir and not my tea time humalog because HUMALOG has a duration of 4 hours and I only had Levemir on board at the time of the hypos which was between 03:00 and 07:00 am
So within 24 hours of these changes, all my blood sugars became stable and night time bg was in range with no hypos at night and less hypos during the day. It's pretty tight controlled now in the past six weeks or so that have elapsed since the changes but I get the occasional wobbler I feel good now, have more energy and glad I made these changes.
Hope this helps!
