I use lantus. Initially took one dose at bedtime & would then have hypos during sleep, changed to morning injection of lantus which resulted in a.m. highs, lantus ran out after 22.5 hours for me. Now I split my lantus. 8 units @ 7a.m. & 6 units @ 10a.m. & it works well for me. I have never heard of toujeo. X
