Alternatives to 3 hour glucose test

I haven’t had my 1 hour test yet, but am terrified of failing.

A friend of mine failed her 1 hour test, but not by much, and instead of doing the 3 hour test, got herself an at home blood sugar metre and just checked her levels after every meal for a week. (With her doctors permission of course)

I really don’t like the idea of having to drink that stuff, and am terrified of getting my blood taken.

I’ll suck it up for the 1 hour test, but wondering if anyone refused the 3 hour, or did some type of alternative to the 3 hour test?
