I had a couple days of classic keto flu symptoms this weekend – nausea, fatigue, , headaches, and diarrhea. I don’t have any keto testing strips around, but I suspect the intermittent fasting I did last week put me into ketosis. I’ve been taking 1/2 tsp salt stirred into a couple cups of water to try to help relieve it. I also took some gravol yesterday for the nausea and some painkillers today for the headache.
I’ll try to be more proactive about keeping my sodium up in the hopes that the intermittent fasting will go well next week. (The last time I donated blood, my blood pressure was 101/65, so there’s really no risk to upping my sodium. I salt food to taste but I guess I don’t quite have enough of a taste for salt to stay on top of my needs.)
