Well ... hate to say this, but that 142 is a diabetic number. Most of us try to keep well below 140. As for what you are ... You may be in the very early stage that some call "pre-diabetes" ... or ... you may actually be a Type 1 or 1.5 on a "honeymoon."
A honeymoon is a period where the pancreas seems to be working perfectly ... but is actually on its way out. This period may last anywhere from a few weeks to a year, after which, high numbers will return, and insulin will be a must. If you have not been tested for Type -- this is the time. In your shoes, in fact, I would get a full set of blood tests to make sure any diagnosis is both accurate and comprehensive. Open-mindedness is an attitude we all must cultivate, albeit one best balanced with a healthy dose of skepticism. Diabetic Reversal/Cure is an extraordinary phenomenon for one to claim. Extraordinary claims require extraordinary evidence, of which, so far, I (sorry to say) have seen none.
