Boy can I relate to these posts. I've been diagnosed about 2 years ago, and my doc and I have been trying since then to get it all to the numbers HE wants. Sometimes I get so frustrated with him because I feel like crap when my numbers are CLOSE to where they should be. I feel like why should I WANT to be at or below 120 when I feel so awful as I get close to it. All of the symptoms you guys mentioned: extreme nausea, shakes, light-headed, and sometimes weakness and blurry vision. I, too, am inclined to grab something to eat just to kill that feeling. Unfortunately, the thing that alleviates the nausea best is a quick drink of 7-up or Pepsi. Now THAT defeats the purpose!
I would think that maybe it was 87 and dropping fast and that caused you to feel bad. Did you wait longer than usual that day to eat? Sometimes if I wait until 1 pm I can start feeling bad because I waited too long and I am in the process of dropping low.
