With TR, you hold doses for less time -- usually 3 - 5 days depending on where the nadir is. Doses are decreased with a drop below 50. With SLGS, you hold each dose for a week and a dose reduction occurs with drops below 90. From looking at SSs on the Relaxed board, I tend to think that many people hold the doses for too long and there is greater risk for glucose toxicity to develop.
I think there's a misconception with regard to the SLGS/Relaxed Lantus approach. There are a number of people who will go to that forum believing that they don't need to test. More specifically, that they don't need to get mid-cycle tests. I also think that there's the misperception that in the TR forum, we're test crazy. We do like data but there's also a recognition that people need to work and have a social life but we do try to underscore that safety is paramount.
FWIW, there is no such term as "relaxed regulation." There was a term needed to describe what amounted to the "other" Lantus board. The relaxed forum is relatively new. There is no research that supports a relaxed approach or that supports the SLGS approach. SLGS was what was available before there was TR and it is not specific to Lantus. With TR, there is published research.
