I was told that one started out on a pill to control b/g, then switched to insulin for over 40 years. She said she did fine all those years on the insulin, but was told that 42 years is to long to be on insulin (she's type 2?) so now she was switched back to a pill (begins with an M) at night and no insulin. Said she's lost tons of weight since off the insulin and felt really bad physically with the switch, but is now adjusting just worried about the weight. Is 42 years to long for a type 2 to be on insulin?
