My blood sugar has seriously gone out of control, had it Dow to 170 or so and all of a sudden my readings are 545, 520, 452, down to 298. I take MetFormin, glipizide, levemir. I am not eating carbs things like bread or pasta. I think it might be the tea I started drinking but still I use to have one or two glasses at night never a problem but now it is. I am lost as to what can be causing it.
