Been on it for about five years. I do basal/bolus but when on the Dafne course they decided to change my morning levemir to humulin I as it's supposed to have an initial kick to fight Dawn. But I still use levemir as my night time long acting. Dawn is ever present in my battle so I'm not sure humulin I is any better than levemir, it was in the beginning but not so much anymore. Use novorapid as my bolus. That doesn't seem to work in the morning either
