I injected insulin for over 20 years before I started using a pump. I wish that I had started pumping as soon as one was available to me. Looking back I can see that my vanity was clouding my judgement. I had several problems with basal insulin that caused low night time BG and DP which caused high BG every morning when I got out of bead. The constant hypos and BG rebounds every day where making me old before my time.
My pump enables me to vary my basal needs, which are very low in the late evenings and extremely high in the early morning hours. When I started pumping I also discovered that my insulin needs throughout the day dropped dramatically my I:C , and sensitivity need to be reduced throughout the day. These small subtle changes where imposable to administer with injected insulin.
The pump change my life:
1). I can sleep soundly at night.
2). My am BG is within target range.
3). I can maintain a normal BMI, seldom am I forced to eat because of too much active insulin.
4). I'm not forced to comply with a injection schedule, in the old days I could never fall asleep early if I injected my night time insulin before 10pm It would cause a hypo about 2am and a sweaty rebound at sunrise....
5). I can eat foods that I never dreamed possible buy having the ability to spread out a bolus it gives me the ability to eat high protein, high fat, foods without high BG 4 or 5 hours down the road.
6). I can reduce or increase my basal insulin on the fly, enabling me to do activity's on short notice...no longer do I have to decide the day before if I'm going to ride a bicycle or even just wash my car without having a low BG event. I even had trouble walking around the block or going to a big department store without going low in the evening hours because I always had to much IOB by 3 or 4 pm every day if I added any extra activity.
