I just leave the house. That's not an issue.
I self fund a CGM. You might get funding for a CGM because of issues with hypo awareness, that's a decision for the CCG. You would need to ask your consultant to submit an individual funding request for this.
Running a little higher (just stay above 5) should help with restoring symptoms. Expecting it do happen in a couple of weeks might be a little ambitious. Symptoms do change over time, so you need to keep careful note of what your new symptoms might be.
You shouldn't have a limited number of test strips available, ask your DSN for help with that. They'll have to write to your GP to get your prescription something more sensible.
