Hi Bopeep
Just read how confused you feel, like us all I think. All advice you have been given seems spot on, so many similarities and different ways of dealing with the problems that arise, it is a brilliant network.
Most type 2 don't get told to test, It is possible to get the Contour meters on line free I believe but buying test strips isn't so cheap. I test when I feel 'not right' generally it is when levels are down around 4 something (that can be on getting up in the morning as well as after walking) sometimes I have forgone lunch and acquired inward trembling, excuse for a cup of hot chocolate.
Now on 2 Metformin a day and have found levels settling down, recently had yearly check and told further check in 6mths (just to make sure it is staying that way or hopefully getting even better).
Night sweats, not every night, apparently down to the diabetes though age must be relevant too!
Golden rule - believe we rule the diabetes not it us, don't become obsessed by it, moderation in everything (that is same for non diabetics) and having regular exercise.
Hope you are beginning to 'see the wood from the trees' you will find what suits you best in time take it steady. Grum.
