Hi Rich,
In my view, your diet looks rather full of the sorts of carbohydrates that many members find makes blood sugar control very difficult. Foods like Weetabix, breads, bananas, rice release a lot of glucose into the bloodstream when digested. Your insulin doses seem to reflect this because they are certainly on the high side.
An average of around 70 units per day is a lot, particularly if you are exercising regularly. I think weight loss will be off the menu unless you get this down to healthier level. That doesn't necessarily mean eating less food, but changing the types of food eaten.
I'd also suggest your overnight hypo problem is a result of taking a large single Lantus dose before bed. That will certainly push you low early in the morning and probably wear off by the evening so your blood sugars will rise then.
Many people find splitting their Lantus solves these problems. One half before bed and the other in the morning and you'll fix the hypo problem and get better coverage throughout the day to boot.
Does any of that ring true?
All the best,
fergus
