Ate a good amount of rice today. I am fatigued. I'm guessing that wasn't caused by eating rice though. Most likely it has been caused by exercising more than typical. I've done a number of pushups and leg squarts, along with walking and swimming. Imagine I'll be fine. Will continue to monitor of course. Tongue looks good and healthy. Back feels fine. there remains a slight amount of pain but nothing that stops me from doing things.
