I am so glad you posted this. While I don't stay in the 70's I do fall into the 70's a couple of hours after eating. I also get shaky. I am on metformin but that doesn't cause lows does it? I am tired of the blood sugar roller coaster. Of course, it had been almost 4 hours since I ate. I went from 116 two hours after eating to 74 in two hours!
