For the past many months I had pretty good control over my blood sugar. If my numbers were high i knew why. But for the past week or two my numbers have been high for no reason. Like now..3 hours after eating my usual breakfast of a 1/2 cup of plain Oatmeal and I’m at 190. The other day I was 220 after skipping lunch I’m also thirsty all the time and peeing alot. Has anyone else had this happen:(
