Ollie sure is a handsome but bouncy boy. I agree with the others, that he seems to need some more juice (as Sienne said, once the current "waiting period" has ended, unless he falls below 50 and therefore requires a reduction). You're starting to see some nice blues now, and you want to try to keep that momentum going. It definitely gets scary at first when you start seeing lower pre-shot numbers, but what usually happens with Lantus is that the curves start to flatten out, meaning that if you start with a low(er) preshot number, you shouldn't see huge, steep dives like you see when a kitty bounces. Whenever you shoot a lower number for the first time, you do want to test at +1 and +2, to see where things are heading. If you do see a big drop, it gives you heads up to either slow the drop with food, or monitor more frequently until things level off.
As Chris said, feel free to post and ask for help any time you feel a need. There are times the board is a little slower, but we're here for you.
Now, Oliver, break that bounce nice and easy, work that juice, and start surfing those pretty blues again!!
