I am not a diabetic. I finally tested again after eating dinner and my sugar got to 90 but the odd thing is the more in range my sugar got the worse my head hurt almost like I had a hangover
You need to treat a low of 40 with glucose tabs. They have 4 grams per tablet and so you can control the dose, and don't risk overeating. For me, two tabs work well, for others they may need more. If you don't have glucose tabs try a glass of oj or some simple sugar such as candy. If you don't have those things, a glass of milk. A chili dog without the bun doesn't have hardly any carbs at all. You need fast acting concentrated carbs.
You don't say if you are a diabetic. If not you might get tested for reactive hypoglycemia or diabetes.
