I was on Mixtard 30 (exact same conposition as Humulin M3) BUT I took Mixtard 30 twice (morning and night) and I took Actrapid for lunch. I don't think it is a good idea to take Humulin M3 three times a day because the insulins will seriously overlap.
I lost nearly 4st by my insulins overlapping. I was delighted but readded 2 due to stopping metformin.
Seeing diabesity specialist on Tuesday as not the same support from separates.
I take humulin M3 twice per day and was told to take it before breakfast and before evening meal. This is also on the information leaflet. There is nothing about taking humulin 3 times per day.
