Took a half-hour walk with some short jogging today, and my pulse is within my normal range (and well below normal human range). It came down a little slower after jogging than usual, but that’s pretty much it.
I also think I may have found out what triggers the sudden and exaggerated bowel activity. It seems to happen a while after a quick carbohydrate meal: A large box of fruit yogurt or two cups of chocolate pudding is sure to trigger it. Judging from the delay I would guess that there is a sugar spike followed by an insulin spike, and the latter is what causes the symptoms. But I may be wrong. It fits the timing though. I can avoid it by walking for half an hour after the meal, as predicted by science. (Physical activity, even very moderate, prevents the insulin spike: The body simply feeds the excess sugar to the muscles in favor of all other energy sources.)
More intriguingly, the symptoms seem similar to my fat poisonings, or “darkening” as I used to call them before I discovered the trigger. I feel cold from inside, but only like my bones had been stored in a fridge rather than a deep freezer. I shiver, but I don’t shake uncontrollably like someone left outside in a blizzard. My bowels start moving, but they don’t twist like a dying snake. I am overwhelmed by a feeling of malaise that does not let me concentrate, but my intelligence is not reduced to half and I don’t panic (at least so far). At the end of the attack I am tired, but not suddenly overwhelmed by sleep. And making the room really warm can pretty much eliminate the attack, rather than just reduce the severity.
Well, that would be interesting if my hypothesis was true. Neither fat nor large amounts of sugar? I would become unbearably healthy, I guess. ^_^ Although I seem to be able to ingest lots of sugar if only I portion it out. I can drink about a liter (quarter of a gallon) of Pepsi over the course of the workday, by not drinking more than about a third of a glass at a time, and then stay off until I get the sugar craving again. So I don’t think I risk starvation because of this.
