It's the morning after a 48 hour fast. I ate dinner last night even though I felt like I could go a bit longer. I had the usual diarrhea about an hour later and went to bed. I got up this morning feeling weak and tired. Everything has been an effort, even lifting my arms in the shower to wash my hair. I don't plan on eating until 6:30 tonight. Anyone know why I'm feeling this way? I don't think it's dehydration as I drink all day and my urine is the usual color.
