Yes, I have been on injections, then went on a pump then back to injections. Have been back on injections for about 7 years now. I'm in New Zealand so things are a little different here. Anyway when I went back on injections I was put on Lantus and Novorapid and for the most part, have had no issues. Though with Lantus, I have had to split my doses so instead of doing it daily I do twice daily and inject novorapid according to carb intake. I went off the pump because of the costs involved and also I too was having issues with DKA but that was more related to an eating disorder I had at the time and my body not being able to cope with just short acting insulin on board. Now, I am having issues with hypo unawareness so that my now specialist wants me to go back on a pump. I am extremely sensitive to insulin and so I have issues with fine tuning my control. I also no longer suffer from the eating disorder, well most days I am good.

I have found it fine reverting back to several injections a day, I have a minimum of 5 a day but I do find it difficult in that I have to be very strict whenever exercising in that I have to do it first thing in the morning before I have any short acting insulin or any food as I have just found it too difficult to exercise any other time of the day as more than likely I will go really hypo if I have any short acting insulin on board.

Something to think about before going back on is you definitely won't have the flexibility that you do with being on a pump BUT you also don't have the issues of kinking lines/sites and the resulting DKA that can happen so quickly when on a pump.

I went off of the pump two years ago and couldn't be happier. I have a Dexcom CGM which really helps me to adjust things. My A1C has stayed about the same.
