I began to take novolog 70/30 august 2014 ( I was on novulin n for many years) I got off of novolog 70/30 due to too many low blood sugar episodes. I was put on novolog and lantus since then. I have lost about 20 lbs since August and would like to know why and what can I do to gain weight' I have had insulin dependent diabetes since I was 17. I am now 64.
