Hi
@ali705 , welcome to the forum.
Are you logging your meals and your insulin doses to see if you can find patterns between the two?
Humalog is a fast acting insulin, are you on a long insulin as well?
How are you dosing your Humalog? Do you take it before every meal? Are you on fixed doses or does the dose depend on the type of meal or your blood glucose before eating?
Sorry for all the questions, they may help in working out what is going on though.
If you've only started the humalog a few days ago, do you have regular contact with your doctor or diabetes nurse to talk your doses through? Finding the right dose is trial and error, so in the beginning doses usually need to be adjusted very often.
