Turns out I having allergic reaction to Humalog. Switched to Novolog and everything is all good again!Some people do have allergic reactions to the newer insulins, talk to your doctor about switching. Have you tried all the type 2 meds- metformin, glipizide, onglyza, januvia, actos, victoza and byetta. Sometimes it is trial and error in finding what works. Also what is your diet like. You say the Levemir knocks you out. What do you normally eat for breakfast. If you are eating a breakfast high in carbs, that may be part of your tiredness. I have to eat a very low carb, high protein and fat breakfast otherwise I tend to nod off, too.
