For the past month I've been out of town for the holidays and I've been feeling nauseated after eating dinner. The people I was visiting suggested that I take my blood sugar after one meal and the meter read 370, twice. The past two days my fasting blood sugar (overnight) has been around 250 and an hour after dinner is 280-340.. I haven't been diagnosed with diabetes but I'm visiting family for the holidays and I can't see one for at least a week.. I'm not really sure what I should do in the meantime. I tried watching what I ate today and it's still 276 after I had dinner (which was just two eggs and half of a small read potato). I've been eating salads and small amounts of food. I've been drinking three or four bottles of water a day.
