The shakes and just felt weak

Got up this afternoon (I work night shift) and started moving some furniture with my wife. All of a sudden, I felt the shakes coming on and just felt really weak. I knew my BG was dropping. I have previously just gotten back on my meds (stupid story) so my #’s are getting back to where they should be after being in the 200-300’s for quite awhile. I went downstairs and took my reading. It was 93. Normally that should be okay right? All I could think of is since my #’s have been extremely high the past month or so, since the meds have kicked in, is it my body adjusting to this? I ate something and within about 20 min or so I felt fine again.
