When I was first dx,d I used about 30 units a day. After about 3 months I didn't need any insulin and convinced myself it was all big mistake and I wasn't diabetic after all. Then after about 4 months of honeymoon my I needed insulin again which rapidly increased to about 45 units/day. Which, more or less is what a use 20 years later. In hindsight I should of used a little insulin when honeymooning as it may have lasted longer.
