Glad to read you have good nurses. They are precious and many people don't have them. You should be able to ask anything you want as often as you need. They are expecting it. However, Metformin can make your digestive system very upset. Most people adapt fairly quickly and it is a valuable and safe medicine. Plus your sysem is probably adapting to lower,ie normal, blood sugar.
You have a lot of new stuff to cope with at the moment, so give it a little while( and ask us) and speak to those lovely nurses.
Do you test yourself?
you should ask for at leat a couple of months supplies, so you can learn what suits you and what doesn't
Hope you fell better soon
