On 20 units of lantus before breakfast, novorapid 3x daily breakfast,lunch and tea, was originally on 8 units before meals but have now attempted to do the card count, reading 8.2 before breakfast, 2 hours later it had climbed to 13 , tested 2 hours later it had dropped to 6.5, are they the type of readings I should be looking for, also on another note, if I find my readings are high before eating should I be adding more units to my novorapid. Any advice appreciated.
