I'm 34 and a type 1.5 like you. I used to need up to 100 units of Novomix insulin/day. But for over 2 years I have controlled my bg with Metformin SR. TBH I think I'm going to stop drinking coffee. It is too strong a diuretic. And I'm going to switch to jasmine (chinese) tea.
I been on Januvia since Wednesday. Amazingly in combination with 2/3 x 500 Glucophage SR my blood sugar is averaging 4.7mmol/l and I don't feel hungry. But I do feel a little tired. I am wondering if I can shake this tiredness off by switching to Galvus?
