I'm Type 2 and have been for 30 years. I take the max dose of metformin AND insulin at bedtime + I walk 30 minutes every day (3 walks of 10" each when we take the girls out) + I try to eat properly.

For the past few years I've done better eating properly and walking. However, during the first years I didnt do as I should have and I have damage to the nerves in my feet and my eyesight is affected some. Sometimes even now I have trouble sleeping at night because my feet tingle and/or feel cold even though my feet are warm. Every night before I go to bed I soak my feet in warm water and then put on warm socks for sleep.

Years ago I lost alot of weight and my diabetes went away. Yes, it is possible because it happened to me... no meds, no shots. Then guess what? I gained the weight back and the diabetes came back. Even now I am pretty sure if I lost a lot of weight, my diabetes would more than likely correct itself. Losing weight is so much more difficult as you get older... I keep trying though.

If your father hasnt seen a doctor, he should and get diagnosed and get some meds. It might be possible for him to control his diabetes (if he has it) with med and diet and exercise. Good Luck!
