No I have not. Most likely its part hereditary(dads and his entire side of the family is diabetic) and part environment. I was heavy drinker in late teens and early twenties and I had a chronic infection that most likely triggers autoimmune responses in the rest of my body including my pancreas. Once I got the infection cured, by removing the infected tissue alot of symptoms have abated and my body has slowly started to recover and I can eat alot more variety of different foods. So who knows but like I said I think its both.
