Re: I think i've messed my body up, help
I agree on the UTI. Did the clinic say anything about that?
Secondly, congrats on controlling your blood sugars successfully for such a long time. That's going to go a long way in controlling your health and risk of complications.
Thirdly, it sounds like a drastic change in insulin is in order. N and R are rarely used for type 1 anymore. Newer insulins are often more successful. These include Levemir and Lantus as the long acting "basal" insulin, and humalog, apidra, or novolog with meals. The down said is 4+ shots a day, the upside is a lot of freedom and more stable blood sugars. The other option is a pump. If insurance doesn't fund this though, it's not likely a viable option.
