It looked like hypoglycemia, left like hypoglycemia, but it wasn’t

I take sylmin before meals. Last night I had for dinner an average size salad consisting of lettuce, cucumbers, peppers and onion. The dressing was low fat and low sugar. Before I go to bed, I take my diabetic medication. At night I take 1 ea Glyb/Metform 2.5/500mg and 2 ea Glumetza 500 mg. I have been on this maintenance for a few years and it works for me. Went to bed at approximately 10:30 PM. Lying in bed I started with what I thought was hypoglycemia. The symptoms were as follows:shakiness, nervousness, dizziness or light-headedness, sleepiness, confusion , anxiety, and weakness. OK I have had it before, I’ll just go out and take my count see it’s in the 70’s and take some soda with sugar and maybe some tablets. Then I’ll calm down, and get some sleep. Took the meter pricked my finger and my count was 235. WOW 45 minutes after take my medication, tried again it was 237. Went back to bed and tried to get to sleep, but my mind was swimming with all kinds of things, from should I go to the emergency room, to what the heck is wrong with me. Got up again in a half hour, after eating a apple, and my count on a different meter, it was 250. OK now I’m freaking out. Finally at a little after 2:00 AM I feel to sleep. I get up at 5:15 AM, so when I awoke this morning I felt better but I was of course tired. This episode scared me to death. Was it something else or did my diabetes have anything to do with it. I am a person that when I get ill, my sugar shoots up to about this stage 225 to 250. I took my sugar this morning and it was 134. A bit high, but the apple didn’t help. Does anyone have any idea what might have happened. Thanks in advance.
