9/30 I actually slept ok last night--in bed around midnight, fell asleep within about 30 minutes, woke up at 7:30 (when my wife got up), tried to fall back asleep for another hour or so before giving up. (I've been trying to sleep extra to help with exercise recovery.) It is now around hour 68 of fasting. I have had some trouble with diarrhea today. From what I've read: - This may be due to drinking coffee in the morning (though no issues on other days when fasting) - It could be an electrolyte imbalance (I may have overdone it on salt) - Not sure what else it would really be caused by - It is more likely to lead to dehydration or other issues if you get diarrhea while fasting... But I otherwise feel fine, so still planning to break the fast around 72 hours. (If I start feeling unwell in any other way I'll break it sooner.) I did have some more salt earlier today, and a few hours ago I took some electrolyte drops in water (I forgot I had those til I was digging around earlier, they have potassium & some other stuff in them too, not just sodium). I was going to exercise normally today (and already did my shoulder rehab exercises), but opted not to just now... I was hoping the stomach issues would be ok by now, but it feels like it probably wouldn't be, don't want to risk it. So, rest day today.
