Hi Sweep,
Your question finally prompted me to sign up - I'm usually a watcher not a 'talker' lol
Basically I was having the same issues as you with my Lantus and hypos and highs. I could never stabilise. Its quite obvious really isnt it to think to take your Lantus during the day when it has most work to do!
Anyway, in answer to your question, it really depends on how confident you are making adjustments to your fast acting insulin (I use novorapid)
I just took my Lantus a few hourse earlier every day for about a week, but I reduced my 22 units to 18 to avoid any nasty hypos and just lived with the higher BG's, adjusting the fast acting to suit. I did bounce around a bit.
Once I'd got to the right time for taking the Lantus, I did BG's 4 -5 times a day to check for unwanted highs and lows and made adjustments to up my Lantus to 21 eventually.
Since then my HBA1C has gone down to the lowest its been for about 15 years! And I feel so much more in control.
When I initially suggested it to my DN, she said not to do it, that I was just becoming less responsive to the insulin and to take more!! Pfft :crazy:
Good luck with the changeover - dont sweat the small stuff - it will settle down
