Lantus and diarrhea

I think my blood sugars are actually doing fairly well on Lantus this time around. I'm using the solostar delivery system vs the whole needle thing. My main issue is that I get diarrhea especially when I am being the most compliant this in itself has made me be uncompliant and skip doses and then I don't have the diarrhea anymore HUH?!?

My husband has been taking for about 2-3 wks and is experiencing severe stomach cramps with diarrhea sometimes after he eats. Sometimes just the cramping but always after a meal. As the day wears on (he takes it at night) the cramping becomes less, but then starts all over next day after taking Lantus before bedtime.
