Hi loudmatthew!
Yes, probably honeymoon. You're also possibly not full Type 1 but LADA - which means a very slow onset and progression - I still produce some of my own insulin after 5 years. Whichever, your insulin needs will increase again after a while - possibly suddenly if Type 1 or gradually if LADA. Keep a close eye on your levels and increase doses as needed.
When I was first diagnosed, I ended up taking 1 unit of basal every two days. Pay close attention to those after food spikes, because if you have LADA you might have strong basal insulin of your own but not have enough first phase insulin to deal with eating - your 12s suggest this is the case - if so, you might want to stop the Levemir for a while and use a unit or two of Humalog for your meals. Obviously discuss with your medical team first.
