I would have to agree with what others are saying, there is little to be gained from testing once a day.
If your fingers are suffering then maybe try other sites, the side of the hand just below the little finger or the ball of the thumb are ones I have seen recommended. Alternatively you may be better to have a day off testing all together to let your fingers recover then go back to testing either side of meals. Just make sure you don't subconsciously decide that as you aren't testing you don't need to watch what you eat, you need to be even more careful.
My meter recommended testing at the side of the finger tip not at the front, this means that you have 20 locations before you have to repeat a place, I can also work out about 3 different sites on each side, one right at the tip almost against the nail, one between the base of the nail and the first joint, and one between these but slightly more to the front of the finger, which normally means I can find a place to stab that isn't too tender.
You might also want to check your lancing devise, mine (the one that came with the codefree meter) has several settings so I can find the one that gets to the blood but doesn't go too deep.
