Hi . . .
If you search my Posts you find several Threads on this same topic (those threads with "Night Hypos" or "Lantus" in the subject title).
After I made my discovery, in January this year, I kept a special eye out on the forum for people reporting similar problems with Lantus. They seemed to come up fairly regularly, every few weeks or so (although it seems to have tailed off recently). I even started replying by Private Message rather than on the open threads, because I was embarrassed to be repeating the same message so often.
Perhaps making this Thread "sticky" may be helpful? (if enough people say that they have experienced the same problem).
Regards,
Antony
