I must look out for the sublingual form of B12, I have not noticed it in H&B, have you had your medication levels checked?, and had your thyroid checked, thats one for the drop in energy and nodding off. I think that when we are in a situation we don't know which way to turn for the best, watching bs levels, looking after the precious kidney, vital, and then trying to find the best plan of food, medication and feeling ok and with it,. I also stay away from the doctors as I find them un-interested and sometimes quick to give a script, even hospital doctors are not recalling back fast enough, for my liking.I must look up Vitamin K, as it too can help the body, I know it is found in strawberries, but uses have been forgotton, google job for me.When you have a hot drink, have tried the fruit teas in place of ordinary tea and coffee?. You being a type 1 it is so much more vital to be selective in your foods etc. Please keep telling us your progress for noe ttfn
