I too had an enforced pump holiday last year when mine broke, and I had a few weeks before obtaining a new one. At the time, I was following a carb-based diet, and snacking reasonably often, so I did find the numerous injections a bit tedious. Even so, I've been wondering about the pros and cons of going back to MDI again...
I've been following a keto diet for almost six months now, and BG control is much more stable, so I could see a way to have only five injections a day - one per meal, plus a split Levemir dose. The main drawbacks as I see them are, first, basal profile not matching my body's needs as closely, and second, lack of IoB calculator for the purpose of correction doses. I was wondering about using a mix of NPH and Levemir to tailor the basal profile a bit...
I've been using a pump for over ten years now, and have infused via my buttocks the whole time. I'm now finding absorption is becoming hit and miss. So I'm trying out angled cannulas in my abdomen. I'm pretty lean, so it's a bit tricky finding suitable sites. I often have to try two or three different abdominal sites before finding one that's comfortable. Even then, it usually becomes uncomfortable after two days.
