My boyfriend has Type 2 and takes his pills, and is eating healthier, BUT he was sneaking donuts and things awhile back. I didn't know this, but he was eating a LOAD of sugar thinking he could because he had his meds.
Now, luckily after he confessed to me months ago and ask for help, he is better. He checks his blood almost daily and at different times. I agree, take it seriously. I mean we all need to take things seriously, diabetes or not. Food for thought, as they say.
I'm glad your guy is doing better! I hope this is now a door that is the way to better health for him.
