Well, as always, YDMV, but if you want lots of customization with your basal insulin that would be a reason to pump. After all these years I’m still on MDI, emphasis on the M, but it works well for me.
For MDI basal insulin, I did not like the Lantus burn or how it worked. Levemir was just fine, but it definitely needed 2x per day and I can see why some people even use it three times a day to meet their needs.
I’ve been using Tresiba for a while now, once a day, and it serves me very well.
Good luck to you. As you probably know there’s lots more information on this site, here are some discussions with more comments:
