While the remark made has some interesting response; I do not except the state of mind issue completely.
My read and experiece is:
a) on liver excess gluscose release - I see no improvement, it appears to be there permently. Stop the pills and schedule and immediately the higher glucose in blood reappears. Taking the met pills has stopped problem but no overall medical impropement on liver yet pill control keeps under control. - - ie drop metformin not option.
b) Insulin side has been far better in that keeping liver under control on metformin and watching diet and exercise and foods eaten has seen improvement and reduction of insulin needed as boost. In past there had been a ton of 75/25 a day - gone and lantus - now gone after working down from 17units a day and down to zero.
I am on the humalog lispro and that started as 10 units per meal and dropped now to 1.5 or less units and sometimes not needed.
So in summary, liver is controlled but no improvement while insulin use has come down indicating improvement.
This is on body that almost rotted out on excess insulin, actos, starlix et all. If your intention is that discipline and hard work correcting mess is state of mind. Possibly.
