@Kris & Teasel The part you quoted from the SLGS Sticky is in the section labelled "In the beginning". Andreea has been at this a while and I wouldn't say she is new anymore.
Andreea, you have shot full dose in the 270's before. 250 is not much lower. You have to think about gradually lowering the number you are comfortable shooting, especially if you are home to monitor. Lantus is great at keeping lower numbers flat. When you shoot a low number, the cycle is much flatter than when you shoot a high number. You don't get as big a drop when you start with a lower preshot number. Experienced people following SLGS will shoot anything above 90. I am not saying you should do that now, but over time and as you gather data, you can shoot lower and lower numbers. Especially when you are home to monitor and see what happens when Tilica gives you a lower number to work with.
I always liked shooting lower numbers, because it was much easier to predict what might happen. When you start with a high preshot number, you could have a dropping cycle or a flat cycle.
For adjusting your schedule, you can move the shot time forward by 1/2 hour once a day, or 15 minutes each cycle. So do tomorrow morning's shot 11.5 hours after the one tonight, and the night time shot at the same time. The next morning, you can shoot again 1/2 hour earlier than the night before.
