With just metformin, do you still feel low sometimes ?Glad you are feeling better. I have to admit I don't carry a meter everywhere with me. But I always have some type of 15 gram carb snack with me to munch on when I feel that "low feeling". If you go to the home page of most meter companies you will usually find free offers. Sometimes I get the free meters just to get the 25 free strips. But it is good to have backup meters and batteries. Also most meter companies will send you free batteries if you call the 1-800 number.
