liz32,
The way I check my basal level is to take my Lantus at normal time and then monitor for the next 16-18 hours with nothing to eat

.
If, during a normal day, my B/G stays within the acceptable range, I know that the basal amount is correct. If, however, the #s are running too low, then basal is too much. If #s are running too high, then basal is too low.
This is my method, I don't know that it'll work for you, but my worst A1c has been 5.7 using this method. Standard A1c has been 5.6.
