| The only reason that peanut butter would help your morning blood sugar is if you were suffering from a low blood sugar in the middle of the night or DP. The peanut butter will help stabilize your blood sugar because of the effect of fats on your blood sugar long term.
If you have doubled your Lantus and you describe and you have not suffered from lowered blood sugar in the morning or during the day, I would suspect that something is wrong with your vial of Lantus. I would ABSOLUTELY not take that much more insulin or increase it until you talk to your doctor. Go back to your 34 units and open a new bottle of Lantus. If you got your supply of Lantus mail order, order a new batch. If you can't do that, I would tell your doctor what you suspect and see if he will write a prescription for one bottle to get at the local pharmacy. |
