@athenalee, and all...Thanks for the information! I'll ck it out tonight. I will order one of the systems tomorrow. I appreciate your concern and the recommendation. Right now, I'm having some serious low glucose readings, all day long. I can't get my glucose above 61 since 1/28! I suspect my autoimmune system is involved with this, but will soon find out, I pray. I'll be at Mayo Monday if not before for tests....doc wants me to go to ED this weekend if I can't get it up. I don't intend on doing that, unless ...I need all your prayers now so we can find the cause and get me up and going!

blessings to you. elizabeth
