Geesh! Eating 30g before bed is a guarantee for morning highs. No end to the bad advice. Infuriating!
Yes, anything starchy (bread, cereal, crackers, pasta, rice, potatoes) hits the bloodstream fast & furiously. Protein & fat digest slowly. Grains are not a good choice for diabetics. Protein for breakfast is best.
Stay away from soy products. Unsweetened almond milk is healthier & very low carb. 2 carbs for 8 ounces.
Have you tried Lactaid? My mother has a problem with lactose & takes Lactaid.
What is your fasting BG in the morning?
If you aren't, would be helpful if you logged your BG before & after meals. If you're always taking 10 units with meals, no need to write that down because it's a constant. Can't know what to do without seeing the patterns to understand where insulin adjustments are needed to tame those numbers.
Three things are critical to using insulin.
1. Your insulin:carb (I:C) ratio. How many units of insulin are needed to cover X number of carbs. People have different ratios for different meals. Breakfast is typically a time of insulin resistance/carb sensitivity, so the ratio is smaller. Lunch, when people are active, tends to have a larger ratio. As our bodies slow down in the evening, dinner ratio can be smaller.
2. You insulin sensivity factor (ISF). How many units of rapid acting insulin are needed to correct highs. For example, 1 unit of Apidra lowers me 60 pts. Everyone is different & I'm a small person. If I'm at 150 & my target is 90, I'd take 1 unit to correct. I have syringes with half unit markings that helps a lot. Need to be cautious with correcting to not end up low. I won't correct less than 2.5-3 hours after injecting. Rapid acting peaks at 90-120 minutes & is usually gone in 4-5 hours. It's called stacking when you inject more with a lot still in your system.
3. Correcting lows. How many grams of pure glucose raise BG how many points? Again, everyone is unique & it's loosely based on weight. One glucose gram raises me 10 pts. If I'm at 60, I use three jelly beans (1 gram each) to get to my target of 90. People tend to overtreat lows.
Realize this sounds overwhelming, but the things we've all learned step by step. Mostly, we've learned on our own through careful trial & error. You can do it.
Doctors never seem to explain this & no wonder that many diabetics have poor control due to lack of education. All they say is, take a certain number of units---arrrgh! Don't know if it's possible for you to be referred to a CDE (certified diabetic educator). She'll give you the ADA carb party line, which you can ignore, but help with your doses would be great.
Using Insulin by John Walsh is a good book.
Understand financial limitations. All you can do is the best you're able to do buying fresh or frozen vegetables & staying away from packaged, expensive junk.
Good for you for writing your governor!
