I do my night lantus at 8pm so I eat them any time between then and 11 depending on how hungry I am, it's the best option because I can't go to bed hungry, and eating anything up to around 15g carbs doesn't seem to do any harm. I'd rather that then go low over night, even though that sometimes seems inevitable. I don't like nuts or anything like that. It's a pain because everything I read that can help control it in some way or another ie peanut butter I don't like.
I eat three meals a day most of the time and basically eat the same things week in week out so that's how I've got my novorapid fixed to the point I have for everything I eat at the moment.
I'll try less lantus and pray it doesn't cause to many highs, otherwise it may be a case of changing my dose between 4 and 6 depending where my blood is to begin with, since my lows happen if my bloods have started in the 4s or 5s.
