To be honest, this just sounds like sugar shock. If your blood sugar rises too fast for insulin to be able to counteract it, then you start getting symptoms like drowsiness, fatigue, and “high-ness.” This can feel good, but it is basically doing damage to your brain, so I am not sure that this would be good long term. Then again, I suppose the same can be said for (hard) drugs.
This feels like it could be exactly the type of thing that causes the car crash in the pilot episode of the Upload TV series.
